13 What you need to know and do in order to upgrade your Arvados installation.
17 # Consult upgrade notes below to see if any manual configuration updates are necessary.
18 # Wait for the cluster to be idle and stop Arvados services.
19 # Install new packages using @apt-get upgrade@ or @yum upgrade@.
20 # Package installation scripts will perform any necessary data migrations.
21 # Restart Arvados services.
25 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.
28 Note to developers: Add new items at the top. Include the date, issue number, commit, and considerations/instructions for those about to upgrade.
30 TODO: extract this information based on git commit messages and generate changelogs / release notes automatically.
33 h3(#master). development master (as of 2020-01-16)
35 h4. "/" prohibited in collection and project names
37 (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.
39 h4. Migrating to centralized config.yml
41 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.
43 h4. Cloud installations only: node manager replaced by arvados-dispatch-cloud
45 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/install-dispatch-cloud.html
47 *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@.
50 <pre><code>~$ <span class="userinput">sudo systemctl --now disable crunch-dispatch-slurm</span>
51 ~$ <span class="userinput">sudo apt-get remove crunch-dispatch-slurm</span>
55 h4. Delete "keep_services" records
57 After all keepproxy and keepstore configurations have been migrated to the centralized configuration file (see below), 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.
59 <notextile><pre><code>$ export ARVADOS_API_HOST=...
60 $ export ARVADOS_API_TOKEN=...
61 $ arv --format=uuid keep_service list | xargs -n1 arv keep_service delete --uuid
62 </code></pre></notextile>
64 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.
66 h4. Keep-balance configuration migration
68 (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.
70 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.
72 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.
74 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.
76 h4. Arv-git-httpd configuration migration
78 (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.
80 h4. Keepstore and keep-web configuration migration
82 keepstore and keep-web no longer support configuration via (previously deprecated) command line configuration flags and environment variables.
84 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.
86 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.
88 h4. Keepproxy configuration migration
90 (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.
92 h4. Jobs API is read-only
94 (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.
96 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@.
98 h4. No longer stripping ':' from strings in serialized database columns
100 (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.
102 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@.
104 h4. Enabling Postgres trigram indexes
106 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.
108 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:
110 <strong>Centos 7</strong>
112 <pre><code>~$ <span class="userinput">sudo yum install -y postgresql95-contrib</span>
113 ~$ <span class="userinput">su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"</span>
117 <strong>RHEL 7</strong>
119 <pre><code>~$ <span class="userinput">sudo yum install -y rh-postgresql95-postgresql-contrib</span>
120 ~$ <span class="userinput">su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"</span>
124 <strong>Debian or Ubuntu</strong>
126 <pre><code>~$ <span class="userinput">sudo apt-get install -y postgresql-contrib-9.5</span>
127 ~$ <span class="userinput">sudo -u postgres psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'</span>
131 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@.
134 h3(#v1_4_1). v1.4.1 (2019-09-20)
136 h4. Centos7 Python 3 dependency upgraded to rh-python36
138 The Python 3 dependency for Centos7 Arvados packages was upgraded from rh-python35 to rh-python36.
140 h3(#v1_4_0). v1.4.0 (2019-06-05)
142 h4. Populating the new file_count and file_size_total columns on the collections table
144 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.
146 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.
148 h4. Stricter collection manifest validation on the API server
150 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.
152 You could set up a new rvm gemset and install the specific arvados gem for testing, like so:
155 <pre><code>~$ <span class="userinput">rvm gemset create rubysdk-test</span>
156 ~$ <span class="userinput">rvm gemset use rubysdk-test</span>
157 ~$ <span class="userinput">gem install arvados -v 1.3.1.20190301212059</span>
161 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:
163 {% codeblock as ruby %}
165 require 'arvados/keep'
174 req = api.collection.index(
175 :select => [:uuid, :created_at, :manifest_text],
176 :include_trash => true, :include_old_versions => true,
177 :limit => batch_size, :offset => offset)
179 invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
183 req[:items].each do |col|
185 Keep::Manifest.validate! col[:manifest_text]
186 rescue Exception => e
187 puts "Collection #{col[:uuid]} manifest not valid"
188 invalid << {uuid: col[:uuid], error: e, created_at: col[:created_at]}
191 puts "Checked #{offset} / #{req[:items_available]} - Invalid: #{invalid.size}"
192 offset += req[:limit]
193 break if offset > req[:items_available]
197 puts "No invalid collection manifests found"
199 invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
203 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.
205 h4. Python packaging change
207 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.
209 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.).
211 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.
213 This can be done by activating the virtualenv outside of the script:
216 <pre>~$ <code class="userinput">source /usr/share/python2.7/dist/python-arvados-python-client/bin/activate</code>
217 (python-arvados-python-client) ~$ <code class="userinput">path-to-the-python-script</code>
221 Or alternatively, by updating the shebang line at the start of the script to:
225 #!/usr/share/python2.7/dist/python-arvados-python-client/bin/python
229 h4. python-arvados-cwl-runner deb/rpm package now conflicts with python-cwltool deb/rpm package
231 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.
233 h4. Centos7 Python 3 dependency upgraded to rh-python35
235 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.
237 h4. Centos7 package for libpam-arvados depends on the python-pam package, which is available from EPEL
239 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.
241 h4. New configuration
243 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.
245 h3(#v1_3_3). v1.3.3 (2019-05-14)
247 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.
249 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.
251 h3(#v1_3_0). v1.3.0 (2018-12-05)
253 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.
255 The @arvados-controller@ component now requires the /etc/arvados/config.yml file to be present.
257 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.
259 h3(#v1_2_1). v1.2.1 (2018-11-26)
261 There are no special upgrade notes for this release.
263 h3(#v1_2_0). v1.2.0 (2018-09-05)
265 h4. Regenerate Postgres table statistics
267 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:
275 tables=`echo "\dt" | psql arvados_production | grep public|awk -e '{print $3}'`
278 echo "echo 'analyze $t' | psql arvados_production"
279 time echo "analyze $t" | psql arvados_production
283 If you also need to do the vacuum, you could adapt the script to run 'vacuum analyze' instead of 'analyze'.
285 h4. New component: arvados-controller
287 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.
289 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.
291 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.
293 h3(#v1_1_4). v1.1.4 (2018-04-10)
295 h4. arvados-cwl-runner regressions (2018-04-05)
297 <strong>Secondary files missing from toplevel workflow inputs</strong>
299 This only affects workflows that rely on implicit discovery of secondaryFiles.
301 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.
303 As an example, the following workflow will fail because the @toplevel_input@ does not declare the @secondaryFiles@ that are expected by @step_input@:
314 step_input: toplevel_input
318 class: CommandLineTool
328 When run, this produces an error like this:
331 cwltool ERROR: [step step1] Cannot make job: Missing required secondary file 'hello.txt.idx' from file object: {
332 "basename": "hello.txt",
334 "location": "keep:ade9d0e032044bd7f58daaecc0d06bc6+51/hello.txt",
342 To fix this error, add the appropriate @secondaryFiles@ section to @toplevel_input@
345 <pre><code>class: Workflow
348 <span class="userinput">toplevel_input:
356 step_input: toplevel_input
360 class: CommandLineTool
371 This bug has been fixed in Arvados release v1.2.0.
373 <strong>Secondary files on default file inputs</strong>
375 @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:
378 class: CommandLineTool
391 When run, this produces an error like this:
394 2018-05-03 10:58:47 cwltool ERROR: Unhandled error, try again with --debug for more information:
395 [Errno 2] File not found: u'hello.txt.idx'
398 To fix this, manually upload the primary and secondary files to keep and explicitly declare @secondaryFiles@ on the default primary file:
401 <pre><code>class: CommandLineTool
407 <span class="userinput">default:
409 location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt
412 location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt.idx</span>
418 This bug has been fixed in Arvados release v1.2.0.
420 h3(#v1_1_3). v1.1.3 (2018-02-08)
422 There are no special upgrade notes for this release.
424 h3(#v1_1_2). v1.1.2 (2017-12-22)

456 h3(#older). Older versions
458 h4. Upgrade slower than usual (2017-06-30)
460 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.
462 * 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.
463 * The conversion runs as a database migration, i.e., during the deb/rpm package upgrade process, while your API server is unavailable.
464 * Expect it to take about 1 minute per 20K jobs that have ever been created/run.
466 h4. Service discovery overhead change in keep-web (2017-06-05)
468 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.
470 * 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.
472 h4. Node manager now has an http endpoint for management (2017-04-12)
474 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.
476 * To enable it, add to your configuration file: <pre>[Manage]
478 port = 8989</pre> (see example configuration files in source:services/nodemanager/doc or https://doc.arvados.org/install/install-nodemanager.html for more info)
479 * The server responds to @http://{address}:{port}/status.json@ with a summary of how many nodes are in each state (booting, busy, shutdown, etc.)
481 h4. New websockets component (2017-03-23)
483 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.
484 * See http://doc.arvados.org/install/install-ws.html for install/upgrade instructions.
485 * Remove the old puma server after the upgrade is complete. Example, with runit: <pre>
486 $ sudo sv down /etc/sv/puma
487 $ sudo rm -r /etc/sv/puma
488 </pre> Example, with systemd: <pre>
489 $ systemctl disable puma
490 $ systemctl stop puma
493 h4. Change of database encoding for hashes and arrays (2017-03-06)
495 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.
497 * Aside from a slight performance improvement, this should have no externally visible effect.
498 * Downgrading past this version is not supported, and is likely to cause errors. If this happens, the solution is to upgrade past this version.
499 * After upgrading, make sure to restart puma and crunch-dispatch-* processes.
501 h4. Docker image format compatibility check (2017-02-03)
503 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.
504 * 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>
505 * 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.
506 * *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.*
508 h4. Debian and RPM packages now have systemd unit files (2016-09-27)
510 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).
512 * On Debian-based systems using systemd, services are enabled automatically when packages are installed.
513 * 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>.
514 * 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>
515 * To migrate from runit to systemd after installing the new packages, we recommend the following procedure:
516 *# Bring down the runit service: "sv down /etc/sv/keep-web"
517 *# Create a JSON configuration file (e.g., /etc/arvados/keep-web/keep-web.yml -- see "keep-web -help")
518 *# Ensure the service is running correctly under systemd: "systemctl status keep-web" / "journalctl -u keep-web"
519 *# Remove the runit service so it doesn't start at next boot
521 ** keep-balance - /etc/arvados/keep-balance/keep-balance.yml
522 ** keep-web - /etc/arvados/keep-web/keep-web.yml
523 ** keepproxy - /etc/arvados/keepproxy/keepproxy.yml
524 ** arvados-git-httpd - /etc/arvados/arv-git-httpd/arv-git-httpd.yml
526 h4. Installation paths for Python modules and script changed (2016-05-31)
528 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.
530 * 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.
531 * 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.
533 h4. Crunchrunner package is required on compute and shell nodes (2016-04-25)
535 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.
537 * On each Debian-based compute node and shell node, run: @sudo apt-get install crunchrunner@
538 * On each Red Hat-based compute node and shell node, run: @sudo yum install crunchrunner@
540 h4. Keep permission signature algorithm change (2016-04-21)
542 Commit "3c88abd":https://dev.arvados.org/projects/arvados/repository/revisions/3c88abd changes the Keep permission signature algorithm.
544 * 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.
545 * Jobs and client operations that are in progress during the upgrade (including arv-put's "resume cache") will fail.
547 h4. Workbench's "Getting Started" popup disabled by default (2015-01-05)
549 Commit "e1276d6e":https://dev.arvados.org/projects/arvados/repository/revisions/e1276d6e disables Workbench's "Getting Started" popup by default.
551 * If you want new users to continue seeing this popup, set @enable_getting_started_popup: true@ in Workbench's @application.yml@ configuration.
553 h4. Crunch jobs now have access to Keep-backed writable scratch storage (2015-12-03)
555 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)
557 * 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
558 * 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.
560 h4. Recommended configuration change for keep-web (2015-11-11)
562 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)
564 * proxy/dns/ssl config should be updated to route "https://download.ClusterID.example.com/" requests to keep-web (alongside the existing "collections" routing)
565 * keep-web command line adds @-attachment-only-host download.ClusterID.example.com@
566 * Workbench config adds @keep_web_download_url@
567 * More info on the (still beta/non-TOC-linked) "keep-web doc page":http://doc.arvados.org/install/install-keep-web.html
569 h4. Stopped containers are now automatically removed on compute nodes (2015-11-04)
571 Commit "1d1c6de":https://dev.arvados.org/projects/arvados/repository/revisions/1d1c6de removes stopped containers (see "#7444":https://dev.arvados.org/issues/7444)
573 * 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.
575 h4. New keep-web service (2015-11-04)
577 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).
579 * 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).
