For Arvados administrators, this page will cover what you need to know and do in order to ensure a smooth upgrade of your Arvados installation.  For general release notes covering features added and bugs fixed, see "Arvados releases":https://arvados.org/releases .

h2. General process

# Consult upgrade notes below to see if any manual configuration updates are necessary.
# Wait for the cluster to be idle and stop Arvados services.
# Make a backup of your database, as a precaution.
# Install new packages using @apt-get upgrade@ or @yum upgrade@.
# Wait for package installation scripts as they perform any necessary data migrations.
# Restart Arvados services.

h2. Upgrade notes

Some versions introduce changes that require special attention when upgrading: e.g., there is a new service to install, or there is a change to the default configuration that you might need to override in order to preserve the old behavior.

{% comment %}
Note to developers: Add new items at the top. Include the date, issue number, commit, and considerations/instructions for those about to upgrade.

h2(#main). development main (as of 2020-12-10)

"Upgrading from 2.1.0":#v2_1_0

h3. New proxy parameters for arvados-controller

In your Nginx configuration file (@/etc/nginx/conf.d/arvados-api-and-controller.conf@), add the following lines to the @location /@ block with @http://controller@ (see "Update nginx configuration":{{site.baseurl}}/install/install-api-server.html#update-nginx for an example) and reload/restart Nginx (@sudo nginx -s reload@).

<pre>
    proxy_set_header      Upgrade           $http_upgrade;
    proxy_set_header      Connection        "upgrade";
</pre>

h3. Changes on the collection's @preserve_version@ attribute semantics

The @preserve_version@ attribute on collections was originally designed to allow clients to persist a preexisting collection version. This forced clients to make 2 requests if the intention is to "make this set of changes in a new version that will be kept", so we have changed the semantics to do just that: When passing @preserve_version=true@ along with other collection updates, the current version is persisted and also the newly created one will be persisted on the next update.

h3. System token requirements

System services now log a warning at startup if any of the system tokens (@ManagementToken@, @SystemRootToken@, and @Collections.BlobSigningKey@) are less than 32 characters, or contain characters other than a-z, A-Z, and 0-9. After upgrading, run @arvados-server config-check@ and update your configuration file if needed to resolve any warnings.

The @API.RailsSessionSecretToken@ configuration key has been removed. Delete this entry from your configuration file after upgrading.

h3. Centos7 Python 3 dependency upgraded to python3

Now that Python 3 is part of the base repository in CentOS 7, the Python 3 dependency for Centos7 Arvados packages was changed from SCL rh-python36 to python3.

h3. ForceLegacyAPI14 option removed

The ForceLegacyAPI14 configuration option has been removed. In the unlikely event it is mentioned in your config file, remove it to avoid "deprecated/unknown config" warning logs.

h2(#v2_1_0). v2.1.0 (2020-10-13)

"Upgrading from 2.0.0":#v2_0_0

h3. LoginCluster conflicts with other Login providers

A satellite cluster that delegates its user login to a central user database must only have `Login.LoginCluster` set, or it will return an error.  This is a change in behavior, previously it would return an error if another login provider was _not_ configured, even though the provider would never be used.

h3. Minimum supported Python version is now 3.5

We no longer publish Python 2 based distribution packages for our Python components. There are equivalent packages based on Python 3, but their names are slightly different. If you were using the Python 2 based packages, you can install the Python 3 based package for a drop in replacement. On Debian and Ubuntu:

<pre>
    apt remove python-arvados-fuse && apt install python3-arvados-fuse
    apt remove python-arvados-python-client && apt install python3-arvados-python-client
    apt remove python-arvados-cwl-runner && apt install python3-arvados-cwl-runner
    apt remove python-crunchstat-summary && apt install python3-crunchstat-summary
    apt remove python-cwltest && apt install python3-cwltest
</pre>

On CentOS:

<pre>
    yum remove python-arvados-fuse && yum install python3-arvados-fuse
    yum remove python-arvados-python-client && yum install python3-arvados-python-client
    yum remove python-arvados-cwl-runner && yum install python3-arvados-cwl-runner
    yum remove python-crunchstat-summary && yum install python3-crunchstat-summary
    yum remove python-cwltest && yum install python3-cwltest
</pre>

h3. Minimum supported Ruby version is now 2.5

The minimum supported Ruby version is now 2.5.  If you are running Arvados on Debian 9 or Ubuntu 16.04, you may need to switch to using RVM or upgrade your OS.  See "Install Ruby and Bundler":../install/ruby.html for more information.

h3. Removing libpam-arvados, replaced with libpam-arvados-go

The Python-based PAM package has been replaced with a version written in Go. See "using PAM for authentication":{{site.baseurl}}/install/setup-login.html#pam for details.

h3. Removing sso-provider

The SSO (single sign-on) component is deprecated and will not be supported in future releases. Existing configurations will continue to work in this release, but you should switch to one of the built-in authentication mechanisms as soon as possible. See "setting up web based login":{{site.baseurl}}/install/setup-login.html for details.

After migrating your configuration, uninstall the @arvados-sso-provider@ package.

h3. S3 signatures

Keepstore now uses "V4 signatures":https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html by default for S3 requests. If you are using Amazon S3, no action is needed; all regions support V4 signatures. If you are using a different S3-compatible service that does not support V4 signatures, add @V2Signature: true@ to your volume driver parameters to preserve the old behavior. See "configuring S3 object storage":{{site.baseurl}}/install/configure-s3-object-storage.html.

h3. New permission system constraints

Some constraints on the permission system have been added, in particular @role@ and @project@ group types now have distinct behavior. These constraints were already de-facto imposed by the Workbench UI, so on most installations the only effect of this migration will be to reassign @role@ groups to the system user and create a @can_manage@ permission link for the previous owner.

# The @group_class@ field must be either @role@ or @project@. Invalid group_class are migrated to @role@.
# A @role@ cannot own things. Anything owned by a role is migrated to a @can_manage@ link and reassigned to the system user.
# Only @role@ and @user@ can have outgoing permission links. Permission links originating from projects are deleted by the migration.
# A @role@ is always owned by the system_user. When a group is created, it creates a @can_manage@ link for the object that would have been assigned to @owner_uuid@.  Migration adds @can_manage@ links and reassigns roles to the system user.  This also has the effect of requiring that all @role@ groups have unique names on the system.  If there is a name collision during migration, roles will be renamed to ensure they are unique.
# A permission link can have the permission level (@name@) updated but not @head_uuid@, @tail_uuid@ or @link_class@.

The @arvados-sync-groups@ tool has been updated to reflect these constraints, so it is important to use the version of @arvados-sync-groups@ that matches the API server version.

Before upgrading, use the following commands to find out which groups and permissions in your database will be automatically modified or deleted during the upgrade.

To determine which groups have invalid @group_class@ (these will be migrated to @role@ groups):

<pre>
arv group list --filters '[["group_class", "not in", ["project", "role"]]]'
</pre>

To list all @role@ groups, which will be reassigned to the system user (unless @owner_uuid@ is already the system user):

<pre>
arv group list --filters '[["group_class", "=", "role"]]'
</pre>

To list which @project@ groups have outgoing permission links (such links are now invalid and will be deleted by the migration):

<pre>
for uuid in $(arv link list --filters '[["link_class", "=", "permission"], ["tail_uuid", "like", "%-j7d0g-%"]]' |
              jq -r .items[].tail_uuid | sort | uniq) ; do
   arv group list --filters '[["group_class", "=", "project"], ["uuid", "=", "'$uuid'"]]' | jq .items
done
</pre>

h4. "Public favorites" moved to their own project

As a side effect of new permission system constraints, "star" links (indicating shortcuts in Workbench) that were previously owned by "All users" (which is now a "role" and cannot own things) will be migrated to a new system project called "Public favorites" which is readable by the "Anonymous users" role.

h2(#v2_0_0). v2.0.0 (2020-02-07)

"Upgrading from 1.4":#v1_4_1

Arvados 2.0 is a major upgrade, with many changes.  Please read these upgrade notes carefully before you begin.

h3. Migrating to centralized config.yml

See "Migrating Configuration":config-migration.html for notes on migrating legacy per-component configuration files to the new centralized @/etc/arvados/config.yml@.

To ensure a smooth transition, the per-component config files continue to be read, and take precedence over the centralized configuration.  Your cluster should continue to function after upgrade but before doing the full configuration migration.  However, several services (keepstore, keep-web, keepproxy) require a minimal `/etc/arvados/config.yml` to start:

<pre>
Clusters:
  zzzzz:
    Services:
      Controller:
        ExternalURL: "https://zzzzz.example.com"
</pre>

h3. Keep-balance configuration migration

(feature "#14714":https://dev.arvados.org/issues/14714 ) The keep-balance service can now be configured using the centralized configuration file at @/etc/arvados/config.yml@. The following command line and configuration options have changed.

You can no longer specify types of keep services to balance via the @KeepServiceTypes@ config option in the legacy config at @/etc/arvados/keep-balance/keep-balance.yml@. If you are still using the legacy config and @KeepServiceTypes@ has a value other than "disk", keep-balance will produce an error.

You can no longer specify individual keep services to balance via the @config.KeepServiceList@ command line option or @KeepServiceList@ legacy config option. Instead, keep-balance will operate on all keepstore servers with @service_type:disk@ as reported by the @arv keep_service list@ command. If you are still using the legacy config, @KeepServiceList@ should be removed or keep-balance will produce an error.

Please see the "config migration guide":{{site.baseurl}}/admin/config-migration.html and "keep-balance install guide":{{site.baseurl}}/install/install-keep-balance.html for more details.

h3. Arv-git-httpd configuration migration

(feature "#14712":https://dev.arvados.org/issues/14712 ) The arv-git-httpd package can now be configured using the centralized configuration file at @/etc/arvados/config.yml@. Configuration via individual command line arguments is no longer available. Please see "arv-git-httpd's config migration guide":{{site.baseurl}}/admin/config-migration.html#arv-git-httpd for more details.

h3. Keepstore and keep-web configuration migration

keepstore and keep-web no longer support configuration via (previously deprecated) command line configuration flags and environment variables.

keep-web now supports the legacy @keep-web.yml@ config format (used by Arvados 1.4) and the new cluster config file format. Please check "keep-web's install guide":{{site.baseurl}}/install/install-keep-web.html for more details.

keepstore now supports the legacy @keepstore.yml@ config format (used by Arvados 1.4) and the new cluster config file format. Please check the "keepstore config migration notes":{{site.baseurl}}/admin/config-migration.html#keepstore and "keepstore install guide":{{site.baseurl}}/install/install-keepstore.html for more details.

h3. Keepproxy configuration migration

(feature "#14715":https://dev.arvados.org/issues/14715 ) Keepproxy can now be configured using the centralized config at @/etc/arvados/config.yml@. Configuration via individual command line arguments is no longer available and the @DisableGet@, @DisablePut@, and @PIDFile@ configuration options are no longer supported. If you are still using the legacy config and @DisableGet@ or @DisablePut@ are set to true or @PIDFile@ has a value, keepproxy will produce an error and fail to start. Please see "keepproxy's config migration guide":{{site.baseurl}}/admin/config-migration.html#keepproxy for more details.

h3. Delete "keep_services" records

After all keepproxy and keepstore configurations have been migrated to the centralized configuration file, all keep_services records you added manually during installation should be removed. System logs from keepstore and keepproxy at startup, as well as the output of @arvados-server config-check@, will remind you to do this.

<notextile><pre><code>$ export ARVADOS_API_HOST=...
$ export ARVADOS_API_TOKEN=...
$ arv --format=uuid keep_service list | xargs -n1 arv keep_service delete --uuid
</code></pre></notextile>

Once these old records are removed, @arv keep_service list@ will instead return the services listed under Services/Keepstore/InternalURLs and Services/Keepproxy/ExternalURL in your centralized configuration file.

h3. Enabling Postgres trigram indexes

Feature "#15106":https://dev.arvados.org/issues/15106 improves the speed and functionality of full text search by introducing trigram indexes on text searchable database columns via a migration. Prior to updating, you must first install the postgresql-contrib package on your system and subsequently run the <code class="userprint">CREATE EXTENSION pg_trgm</code> SQL command on the arvados_production database as a postgres superuser.

The "postgres-contrib package":https://www.postgresql.org/docs/10/contrib.html has been supported since PostgreSQL version 9.4. The version of the contrib package should match the version of your PostgreSQL installation. Using 9.5 as an example, the package can be installed and the extension enabled using the following:

<strong>Centos 7</strong>
<notextile>
<pre><code>~$ <span class="userinput">sudo yum install -y postgresql95-contrib</span>
~$ <span class="userinput">su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"</span>
</code></pre>
</notextile>

<strong>RHEL 7</strong>
<notextile>
<pre><code>~$ <span class="userinput">sudo yum install -y rh-postgresql95-postgresql-contrib</span>
~$ <span class="userinput">su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"</span>
</code></pre>
</notextile>

<strong>Debian or Ubuntu</strong>
<notextile>
<pre><code>~$ <span class="userinput">sudo apt-get install -y postgresql-contrib-9.5</span>
~$ <span class="userinput">sudo -u postgres psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'</span>
</code></pre>
</notextile>

Subsequently, the <code class="userinput">psql -d 'arvados_production' -c '\dx'</code> command will display the installed extensions for the arvados_production database. This list should now contain @pg_trgm@.

h3. New Workbench 2

Workbench 2 is now ready for regular use.  Follow the instructions to "install workbench 2":../install/install-workbench2-app.html

h3. New property vocabulary format for Workbench2

(feature "#14151":https://dev.arvados.org/issues/14151) Workbench2 supports a new vocabulary format and it isn't compatible with the previous one, please read the "workbench2 vocabulary format admin page":{{site.baseurl}}/admin/workbench2-vocabulary.html for more information.

h3. Cloud installations only: node manager replaced by arvados-dispatch-cloud

Node manager is deprecated and replaced by @arvados-dispatch-cloud@.  No automated config migration is available.  Follow the instructions to "install the cloud dispatcher":../install/crunch2-cloud/install-dispatch-cloud.html

*Only one dispatch process should be running at a time.* If you are migrating a system that currently runs Node manager and @crunch-dispatch-slurm@, it is safest to remove the @crunch-dispatch-slurm@ service entirely before installing @arvados-dispatch-cloud@.

<notextile>
<pre><code>~$ <span class="userinput">sudo systemctl --now disable crunch-dispatch-slurm</span>
~$ <span class="userinput">sudo apt-get remove crunch-dispatch-slurm</span>
</code></pre>
</notextile>

h3. Jobs API is read-only

(task "#15133":https://dev.arvados.org/issues/15133 ) The legacy 'jobs' API is now read-only.  It has been superceded since Arvados 1.1 by containers / container_requests (aka crunch v2).  Arvados installations since the end of 2017 (v1.1.0) have probably only used containers, and are unaffected by this change.

So that older Arvados sites don't lose access to legacy records, the API has been converted to read-only.  Creating and updating jobs (and related types job_task, pipeline_template and pipeline_instance) is disabled and much of the business logic related has been removed, along with various other code specific to the jobs API.  Specifically, the following programs associated with the jobs API have been removed: @crunch-dispatch.rb@, @crunch-job@, @crunchrunner@, @arv-run-pipeline-instance@, @arv-run@.

h3. "/" prohibited in collection and project names

(issue "#15836":https://dev.arvados.org/issues/15836) By default, Arvados now rejects new names containing the @/@ character when creating or renaming collections and projects. Previously, these names were permitted, but the resulting objects were invisible in the WebDAV "home" tree. If you prefer, you can restore the previous behavior, and optionally configure a substitution string to make the affected objects accessible via WebDAV. See @ForwardSlashNameSubstitution@ in the "configuration reference":config.html.

h3. No longer stripping ':' from strings in serialized database columns

(bug "#15311":https://dev.arvados.org/issues/15311 ) Strings read from serialized columns in the database with a leading ':' would have the ':' stripped after loading the record.  This behavior existed due to legacy serialization behavior which stored Ruby symbols with a leading ':'.  Unfortunately this corrupted fields where the leading ":" was intentional.  This behavior has been removed.

You can test if any records in your database are affected by going to the API server directory and running @bundle exec rake symbols:check@.  This will report which records contain fields with a leading ':' that would previously have been stripped.  If there are records to be updated, you can update the database using @bundle exec rake symbols:stringify@.

h3. Scoped tokens should use PATCH for updates

The API server accepts both PUT and PATCH for updates, but they will be normalized to PATCH by arvados-controller.  Scoped tokens should be updated accordingly.



h2(#v1_4_1). v1.4.1 (2019-09-20)

"Upgrading from 1.4.0":#v1_4_0

h3. Centos7 Python 3 dependency upgraded to rh-python36

The Python 3 dependency for Centos7 Arvados packages was upgraded from rh-python35 to rh-python36.

h2(#v1_4_0). v1.4.0 (2019-06-05)

"Upgrading from 1.3.3":#v1_3_3

h3. Populating the new file_count and file_size_total columns on the collections table

As part of story "#14484":https://dev.arvados.org/issues/14484, two new columns were added to the collections table in a database migration. If your installation has a large collections table, this migration may take some time. We've seen it take ~5 minutes on an installation with 250k collections, but your mileage may vary.

The new columns are initialized with a zero value. In order to populate them, it is necessary to run a script called <code class="userinput">populate-file-info-columns-in-collections.rb</code> from the scripts directory of the API server. This can be done out of band, ideally directly after the API server has been upgraded to v1.4.0.

h3. Stricter collection manifest validation on the API server

As a consequence of "#14482":https://dev.arvados.org/issues/14482, the Ruby SDK does a more rigorous collection manifest validation. Collections created after 2015-05 are unlikely to be invalid, however you may check for invalid manifests using the script below.

You could set up a new rvm gemset and install the specific arvados gem for testing, like so:

<notextile>
<pre><code>~$ <span class="userinput">rvm gemset create rubysdk-test</span>
~$ <span class="userinput">rvm gemset use rubysdk-test</span>
~$ <span class="userinput">gem install arvados -v 1.3.1.20190301212059</span>
</code></pre>
</notextile>

Next, you can run the following script using admin credentials, it will scan the whole collection database and report any collection that didn't pass the check:

{% codeblock as ruby %}
require 'arvados'
require 'arvados/keep'

api = Arvados.new
offset = 0
batch_size = 100
invalid = []

while true
    begin
        req = api.collection.index(
            :select => [:uuid, :created_at, :manifest_text],
            :include_trash => true, :include_old_versions => true,
            :limit => batch_size, :offset => offset)
    rescue
        invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
        raise
    end

    req[:items].each do |col|
        begin
            Keep::Manifest.validate! col[:manifest_text]
        rescue Exception => e
            puts "Collection #{col[:uuid]} manifest not valid"
            invalid << {uuid: col[:uuid], error: e, created_at: col[:created_at]}
        end
    end
    puts "Checked #{offset} / #{req[:items_available]} - Invalid: #{invalid.size}"
    offset += req[:limit]
    break if offset > req[:items_available]
end

if invalid.empty?
    puts "No invalid collection manifests found"
else
    invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
end
{% endcodeblock %}

The script will return a final report enumerating any invalid collection by UUID, with its creation date and error message so you can take the proper correction measures, if needed.

h3. Python packaging change

As part of story "#9945":https://dev.arvados.org/issues/9945, the distribution packaging (deb/rpm) of our Python packages has changed. These packages now include a built-in virtualenv to reduce dependencies on system packages. We have also stopped packaging and publishing backports for all the Python dependencies of our packages, as they are no longer needed.

One practical consequence of this change is that the use of the Arvados Python SDK (aka "import arvados") will require a tweak if the SDK was installed from a distribution package. It now requires the loading of the virtualenv environment from our packages. The "Install documentation for the Arvados Python SDK":/sdk/python/sdk-python.html reflects this change. This does not affect the use of the command line tools (e.g. arv-get, etc.).

Python scripts that rely on the distribution Arvados Python SDK packages to import the Arvados SDK will need to be tweaked to load the correct Python environment.

This can be done by activating the virtualenv outside of the script:

<notextile>
<pre>~$ <code class="userinput">source /usr/share/python2.7/dist/python-arvados-python-client/bin/activate</code>
(python-arvados-python-client) ~$ <code class="userinput">path-to-the-python-script</code>
</pre>
</notextile>

Or alternatively, by updating the shebang line at the start of the script to:

<notextile>
<pre>
#!/usr/share/python2.7/dist/python-arvados-python-client/bin/python
</pre>
</notextile>

h3. python-arvados-cwl-runner deb/rpm package now conflicts with python-cwltool deb/rpm package

As part of story "#9945":https://dev.arvados.org/issues/9945, the distribution packaging (deb/rpm) of our Python packages has changed. The python-arvados-cwl-runner package now includes a version of cwltool. If present, the python-cwltool and cwltool distribution packages will need to be uninstalled before the python-arvados-cwl-runner deb or rpm package can be installed.

h3. Centos7 Python 3 dependency upgraded to rh-python35

As part of story "#9945":https://dev.arvados.org/issues/9945, the Python 3 dependency for Centos7 Arvados packages was upgraded from SCL python33 to rh-python35.

h3. Centos7 package for libpam-arvados depends on the python-pam package, which is available from EPEL

As part of story "#9945":https://dev.arvados.org/issues/9945, it was discovered that the Centos7 package for libpam-arvados was missing a dependency on the python-pam package, which is available from the EPEL repository. The dependency has been added to the libpam-arvados package. This means that going forward, the EPEL repository will need to be enabled to install libpam-arvados on Centos7.

h3. New configuration

Arvados is migrating to a centralized configuration file for all components.  During the migration, legacy configuration files will continue to be loaded.  See "Migrating Configuration":config-migration.html for details.

h2(#v1_3_3). v1.3.3 (2019-05-14)

"Upgrading from 1.3.0":#v1_3_0

This release corrects a potential data loss issue, if you are running Arvados 1.3.0 or 1.3.1 we strongly recommended disabling @keep-balance@ until you can upgrade to 1.3.3 or 1.4.0. With keep-balance disabled, there is no chance of data loss.

We've put together a "wiki page":https://dev.arvados.org/projects/arvados/wiki/Recovering_lost_data which outlines how to recover blocks which have been put in the trash, but not yet deleted, as well as how to identify any collections which have missing blocks so that they can be regenerated. The keep-balance component has been enhanced to provide a list of missing blocks and affected collections and we've provided a "utility script":https://github.com/arvados/arvados/blob/master/tools/keep-xref/keep-xref.py  which can be used to identify the workflows that generated those collections and who ran those workflows, so that they can be rerun.

h2(#v1_3_0). v1.3.0 (2018-12-05)

"Upgrading from 1.2":#v1_2_0

This release includes several database migrations, which will be executed automatically as part of the API server upgrade. On large Arvados installations, these migrations will take a while. We've seen the upgrade take 30 minutes or more on installations with a lot of collections.

The @arvados-controller@ component now requires the /etc/arvados/config.yml file to be present.

Support for the deprecated "jobs" API is broken in this release.  Users who rely on it should not upgrade.  This will be fixed in an upcoming 1.3.1 patch release, however users are "encouraged to migrate":upgrade-crunch2.html as support for the "jobs" API will be dropped in an upcoming release.  Users who are already using the "containers" API are not affected.

h2(#v1_2_1). v1.2.1 (2018-11-26)

There are no special upgrade notes for this release.

h2(#v1_2_0). v1.2.0 (2018-09-05)

"Upgrading from 1.1.2 or 1.1.3":#v1_1_2

h3. Regenerate Postgres table statistics

It is recommended to regenerate the table statistics for Postgres after upgrading to v1.2.0. If autovacuum is enabled on your installation, this script would do the trick:

<pre>
#!/bin/bash

set -e
set -u

tables=`echo "\dt" | psql arvados_production | grep public|awk -e '{print $3}'`

for t in $tables; do
    echo "echo 'analyze $t' | psql arvados_production"
    time echo "analyze $t" | psql arvados_production
done
</pre>

If you also need to do the vacuum, you could adapt the script to run 'vacuum analyze' instead of 'analyze'.

h3. New component: arvados-controller

Commit "db5107dca":https://dev.arvados.org/projects/arvados/repository/revisions/db5107dca adds a new system service, arvados-controller. More detail is available in story "#13496":https://dev.arvados.org/issues/13497.

To add the Arvados Controller to your system please refer to the "installation instructions":../install/install-api-server.html after upgrading your system to 1.2.0.

Verify your setup by confirming that API calls appear in the controller's logs (_e.g._, @journalctl -fu arvados-controller@) while loading a workbench page.

h3. arvados-cwl-runner regressions (2018-04-05)

<strong>Secondary files missing from toplevel workflow inputs</strong>

This only affects workflows that rely on implicit discovery of secondaryFiles.

If a workflow input does not declare @secondaryFiles@ corresponding to the @secondaryFiles@ of workflow steps which use the input, the workflow would inconsistently succeed or fail depending on whether the input values were specified as local files or referenced an existing collection (and whether the existing collection contained the secondary files or not).  To ensure consistent behavior, the workflow is now required to declare in the top level workflow inputs any secondaryFiles that are expected by workflow steps.

As an example, the following workflow will fail because the @toplevel_input@ does not declare the @secondaryFiles@ that are expected by @step_input@:

<pre>
class: Workflow
cwlVersion: v1.0
inputs:
  toplevel_input: File
outputs: []
steps:
  step1:
    in:
      step_input: toplevel_input
    out: []
    run:
      id: sub
      class: CommandLineTool
      inputs:
        step_input:
          type: File
          secondaryFiles:
            - .idx
      outputs: []
      baseCommand: echo
</pre>

When run, this produces an error like this:

<pre>
cwltool ERROR: [step step1] Cannot make job: Missing required secondary file 'hello.txt.idx' from file object: {
    "basename": "hello.txt",
    "class": "File",
    "location": "keep:ade9d0e032044bd7f58daaecc0d06bc6+51/hello.txt",
    "size": 0,
    "nameroot": "hello",
    "nameext": ".txt",
    "secondaryFiles": []
}
</pre>

To fix this error, add the appropriate @secondaryFiles@ section to @toplevel_input@

<notextile>
<pre><code>class: Workflow
cwlVersion: v1.0
inputs:
  <span class="userinput">toplevel_input:
    type: File
    secondaryFiles:
      - .idx</span>
outputs: []
steps:
  step1:
    in:
      step_input: toplevel_input
    out: []
    run:
      id: sub
      class: CommandLineTool
      inputs:
        step_input:
          type: File
          secondaryFiles:
            - .idx
      outputs: []
      baseCommand: echo
</code></pre>
</notextile>

This bug has been fixed in Arvados release v1.2.0.

<strong>Secondary files on default file inputs</strong>

@File@ inputs that have default values and also expect @secondaryFiles@ and will fail to upload default @secondaryFiles@.  As an example, the following case will fail:

<pre>
class: CommandLineTool
inputs:
  step_input:
    type: File
    secondaryFiles:
      - .idx
    default:
      class: File
      location: hello.txt
outputs: []
baseCommand: echo
</pre>

When run, this produces an error like this:

<pre>
2018-05-03 10:58:47 cwltool ERROR: Unhandled error, try again with --debug for more information:
  [Errno 2] File not found: u'hello.txt.idx'
</pre>

To fix this, manually upload the primary and secondary files to keep and explicitly declare @secondaryFiles@ on the default primary file:

<notextile>
<pre><code>class: CommandLineTool
inputs:
  step_input:
    type: File
    secondaryFiles:
      - .idx
    <span class="userinput">default:
      class: File
      location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt
      secondaryFiles:
       - class: File
         location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt.idx</span>
outputs: []
baseCommand: echo
</code></pre>
</notextile>

This bug has been fixed in Arvados release v1.2.0.

h2(#older). Older versions

h3. Upgrade slower than usual (2017-06-30)

As part of story "#11807":https://dev.arvados.org/issues/11807, commit "55aafbb":https://dev.arvados.org/projects/arvados/repository/revisions/55aafbb converts old "jobs" database records from YAML to JSON, making the upgrade process slower than usual.

* The migration can take some time if your database contains a substantial number of YAML-serialized rows (i.e., you installed Arvados before March 3, 2017 "660a614":https://dev.arvados.org/projects/arvados/repository/revisions/660a614 and used the jobs/pipelines APIs). Otherwise, the upgrade will be no slower than usual.
* The conversion runs as a database migration, i.e., during the deb/rpm package upgrade process, while your API server is unavailable.
* Expect it to take about 1 minute per 20K jobs that have ever been created/run.

h3. Service discovery overhead change in keep-web (2017-06-05)

As part of story "#9005":https://dev.arvados.org/issues/9005, commit "cb230b0":https://dev.arvados.org/projects/arvados/repository/revisions/cb230b0 reduces service discovery overhead in keep-web requests.

* When upgrading keep-web _or keepproxy_ to/past this version, make sure to update API server as well. Otherwise, a bad token in a request can cause keep-web to fail future requests until either keep-web restarts or API server gets upgraded.

h3. Node manager now has an http endpoint for management (2017-04-12)

As part of story "#11349":https://dev.arvados.org/issues/11349, commit "2c094e2":https://dev.arvados.org/projects/arvados/repository/revisions/2c094e2 adds a "management" http server to nodemanager.

* To enable it, add to your configuration file: <pre>[Manage]
  address = 127.0.0.1
  port = 8989</pre>
* The server responds to @http://{address}:{port}/status.json@ with a summary of how many nodes are in each state (booting, busy, shutdown, etc.)

h3. New websockets component (2017-03-23)

As part of story "#10766":https://dev.arvados.org/issues/10766, commit "e8cc0d7":https://dev.arvados.org/projects/arvados/repository/revisions/e8cc0d7 replaces puma with arvados-ws as the recommended websocket server.
* See http://doc.arvados.org/install/install-ws.html for install/upgrade instructions.
* Remove the old puma server after the upgrade is complete. Example, with runit: <pre>
$ sudo sv down /etc/sv/puma
$ sudo rm -r /etc/sv/puma
</pre> Example, with systemd: <pre>
$ systemctl disable puma
$ systemctl stop puma
</pre>

h3. Change of database encoding for hashes and arrays (2017-03-06)

As part of story "#11168":https://dev.arvados.org/issues/11168, commit "660a614":https://dev.arvados.org/projects/arvados/repository/revisions/660a614 uses JSON instead of YAML to encode hashes and arrays in the database.

* Aside from a slight performance improvement, this should have no externally visible effect.
* Downgrading past this version is not supported, and is likely to cause errors. If this happens, the solution is to upgrade past this version.
* After upgrading, make sure to restart puma and crunch-dispatch-* processes.

h3. Docker image format compatibility check (2017-02-03)

As part of story "#10969":https://dev.arvados.org/issues/10969, commit "74a9dec":https://dev.arvados.org/projects/arvados/repository/revisions/74a9dec introduces a Docker image format compatibility check: the @arv keep docker@ command prevents users from inadvertently saving docker images that compute nodes won't be able to run.
* If your compute nodes run a version of *docker older than 1.10* you must override the default by adding to your API server configuration (@/etc/arvados/api/application.yml@): <pre><code class="yaml">docker_image_formats: ["v1"]</code></pre>
* Refer to the comments above @docker_image_formats@ in @/var/www/arvados-api/current/config/application.default.yml@ or source:services/api/config/application.default.yml or issue "#10969":https://dev.arvados.org/issues/10969 for more detail.
* *NOTE:* This does *not* include any support for migrating existing Docker images from v1 to v2 format. This will come later: for now, sites running Docker 1.9 or earlier should still *avoid upgrading Docker further than 1.9.*

h3. Debian and RPM packages now have systemd unit files (2016-09-27)

Several Debian and RPM packages -- keep-balance ("d9eec0b":https://dev.arvados.org/projects/arvados/repository/revisions/d9eec0b), keep-web ("3399e63":https://dev.arvados.org/projects/arvados/repository/revisions/3399e63), keepproxy ("6de67b6":https://dev.arvados.org/projects/arvados/repository/revisions/6de67b6), and arvados-git-httpd ("9e27ddf":https://dev.arvados.org/projects/arvados/repository/revisions/9e27ddf) -- now enable their respective components using systemd. These components prefer YAML configuration files over command line flags ("3bbe1cd":https://dev.arvados.org/projects/arvados/repository/revisions/3bbe1cd).

* On Debian-based systems using systemd, services are enabled automatically when packages are installed.
* On RedHat-based systems using systemd, unit files are installed but services must be enabled explicitly: e.g., <code>"sudo systemctl enable keep-web; sudo systemctl start keep-web"</code>.
* The new systemd-supervised services will not start up successfully until configuration files are installed in /etc/arvados/: e.g., <code>"Sep 26 18:23:55 62751f5bb946 keep-web[74]: 2016/09/26 18:23:55 open /etc/arvados/keep-web/keep-web.yml: no such file or directory"</code>
* To migrate from runit to systemd after installing the new packages, we recommend the following procedure:
*# Bring down the runit service: "sv down /etc/sv/keep-web"
*# Create a JSON configuration file (e.g., /etc/arvados/keep-web/keep-web.yml -- see "keep-web -help")
*# Ensure the service is running correctly under systemd: "systemctl status keep-web" / "journalctl -u keep-web"
*# Remove the runit service so it doesn't start at next boot
* Affected services:
** keep-balance - /etc/arvados/keep-balance/keep-balance.yml
** keep-web - /etc/arvados/keep-web/keep-web.yml
** keepproxy - /etc/arvados/keepproxy/keepproxy.yml
** arvados-git-httpd - /etc/arvados/arv-git-httpd/arv-git-httpd.yml

h3. Installation paths for Python modules and script changed (2016-05-31)

Commits "ae72b172c8":https://dev.arvados.org/projects/arvados/repository/revisions/ae72b172c8 and "3aae316c25":https://dev.arvados.org/projects/arvados/repository/revisions/3aae316c25 change the filesystem location where Python modules and scripts are installed.

* Previous packages installed these files to the distribution's preferred path under @/usr/local@ (or the equivalent location in a Software Collection).  Now they get installed to a path under @/usr@.  This improves compatibility with other Python packages provided by the distribution.  See "#9242":https://dev.arvados.org/issues/9242 for more background.
* If you simply import Python modules from scripts, or call Python tools relying on $PATH, you don't need to make any changes.  If you have hardcoded full paths to some of these files (e.g., in symbolic links or configuration files), you will need to update those paths after this upgrade.

h3. Crunchrunner package is required on compute and shell nodes (2016-04-25)

Commit "eebcb5e":https://dev.arvados.org/projects/arvados/repository/revisions/eebcb5e requires the crunchrunner package to be installed on compute nodes and shell nodes in order to run CWL workflows.

* On each Debian-based compute node and shell node, run: @sudo apt-get install crunchrunner@
* On each Red Hat-based compute node and shell node, run: @sudo yum install crunchrunner@

h3. Keep permission signature algorithm change (2016-04-21)

Commit "3c88abd":https://dev.arvados.org/projects/arvados/repository/revisions/3c88abd changes the Keep permission signature algorithm.

* All software components that generate signatures must be upgraded together. These are: keepstore, API server, keep-block-check, and keep-rsync. For example, if keepstore < 0.1.20160421183420 but API server >= 0.1.20160421183420, clients will not be able to read or write data in Keep.
* Jobs and client operations that are in progress during the upgrade (including arv-put's "resume cache") will fail.

h3. Workbench's "Getting Started" popup disabled by default (2015-01-05)

Commit "e1276d6e":https://dev.arvados.org/projects/arvados/repository/revisions/e1276d6e disables Workbench's "Getting Started" popup by default.

* If you want new users to continue seeing this popup, set @enable_getting_started_popup: true@ in Workbench's @application.yml@ configuration.

h3. Crunch jobs now have access to Keep-backed writable scratch storage (2015-12-03)

Commit "5590c9ac":https://dev.arvados.org/projects/arvados/repository/revisions/5590c9ac makes a Keep-backed writable scratch directory available in crunch jobs (see "#7751":https://dev.arvados.org/issues/7751)

* All compute nodes must be upgraded to arvados-fuse >= 0.1.2015112518060 because crunch-job uses some new arv-mount flags (--mount-tmp, --mount-by-pdh) introduced in merge "346a558":https://dev.arvados.org/projects/arvados/repository/revisions/346a558
* Jobs will fail if the API server (in particular crunch-job from the arvados-cli gem) is upgraded without upgrading arvados-fuse on compute nodes.

h3. Recommended configuration change for keep-web (2015-11-11)

Commit "1e2ace5":https://dev.arvados.org/projects/arvados/repository/revisions/1e2ace5 changes recommended config for keep-web (see "#5824":https://dev.arvados.org/issues/5824)

* proxy/dns/ssl config should be updated to route "https://download.ClusterID.example.com/" requests to keep-web (alongside the existing "collections" routing)
* keep-web command line adds @-attachment-only-host download.ClusterID.example.com@
* Workbench config adds @keep_web_download_url@
* More info on the (still beta/non-TOC-linked) "keep-web doc page":http://doc.arvados.org/install/install-keep-web.html

h3. Stopped containers are now automatically removed on compute nodes (2015-11-04)

Commit "1d1c6de":https://dev.arvados.org/projects/arvados/repository/revisions/1d1c6de removes stopped containers (see "#7444":https://dev.arvados.org/issues/7444)

* arvados-docker-cleaner removes _all_ docker containers as soon as they exit, effectively making @docker run@ default to @--rm@. If you run arvados-docker-cleaner on a host that does anything other than run crunch-jobs, and you still want to be able to use @docker start@, read the "new doc page":http://doc.arvados.org/install/install-compute-node.html to learn how to turn this off before upgrading.

h3. New keep-web service (2015-11-04)

Commit "21006cf":https://dev.arvados.org/projects/arvados/repository/revisions/21006cf adds a new keep-web service (see "#5824":https://dev.arvados.org/issues/5824).

* Nothing relies on keep-web yet, but early adopters can install it now by following http://doc.arvados.org/install/install-keep-web.html (it is not yet linked in the TOC).
