-
-Arvados 2.0 migrates to a centralized configuration file for all components. The centralized Arvados configuration is @/etc/arvados/config.yml@. Components that support the new centralized configuration are listed below. During the migration period, legacy configuration files are still loaded and take precedence over the centralized configuration file.
-
-h2. API server
-
-The legacy API server configuration is stored in @config/application.yml@ and @config/database.yml@. After migration to @/etc/arvados/config.yml@, both of these files should be moved out of the way and/or deleted.
-
-Change to the API server directory and use the following commands:
-
-<pre>
-$ RAILS_ENV=production bin/rake config:migrate > config.yml
-$ cp config.yml /etc/arvados/config.yml
-</pre>
-
-This will print the contents of @config.yml@ after merging the legacy @application.yml@ and @database.yml@ into the existing systemwide @config.yml@. It may be redirected to a file and copied to @/etc/arvados/config.yml@ (it is safe to copy over, all configuration items from the existing @/etc/arvados/config.yml@ will be included in the migrated output).
-
-If you wish to update @config.yml@ configuration by hand, or check that everything has been migrated, use @config:diff@ to print configuration items that differ between @application.yml@ and the system @config.yml@.
-
-<pre>
-$ RAILS_ENV=production bin/rake config:diff
-</pre>
-
-This command will also report if no migrations are required.
-
-h2. Workbench
-
-The legacy workbench configuration is stored in @config/application.yml@. After migration to @/etc/arvados/config.yml@, this file should be moved out of the way and/or deleted.
-
-Change to the workbench server directory and use the following commands:
-
-<pre>
-$ RAILS_ENV=production bin/rake config:migrate > config.yml
-$ cp config.yml /etc/arvados/config.yml
-</pre>
-
-This will print the contents of @config.yml@ after merging the legacy @application.yml@ into the existing systemwide @config.yml@. It may be redirected to a file and copied to @/etc/arvados/config.yml@ (it is safe to copy over, all configuration items from the existing @/etc/arvados/config.yml@ will be included in the migrated output).
-
-If you wish to update @config.yml@ configuration by hand, or check that everything has been migrated, use @config:diff@ to print configuration items that differ between @application.yml@ and the system @config.yml@.
-
-<pre>
-$ RAILS_ENV=production bin/rake config:diff
-</pre>
-
-This command will also report if no migrations are required.

-h2. keepstore, keep-web, crunch-dispatch-slurm, arvados-ws, keepproxy, arv-git-httpd, keep-balance
-
-The legacy config for each component (loaded from @/etc/arvados/component/component.yml@ or a different location specified via the -legacy-component-config command line argument) takes precedence over the centralized config. After you migrate everything from the legacy config to the centralized config, you should delete @/etc/arvados/component/component.yml@ and/or stop using the corresponding -legacy-component-config argument.
-
-To migrate a component configuration, do this on each node that runs an Arvados service:
-
-# Ensure that the latest @config.yml@ is installed on the current node
-# Install @arvados-server@ using @apt-get@ or @yum@.
-# Run @arvados-server config-check@, review and apply the recommended changes to @/etc/arvados/config.yml@
-# After applying changes, re-run @arvados-server config-check@ again to check for additional warnings and recommendations.
-# When you are satisfied, delete the legacy config file, restart the service, and check its startup logs.
-# Copy the updated @config.yml@ file to your next node, and repeat the process there.
-# When you have a @config.yml@ file that includes all volumes on all keepstores, it is important to add a 'Rendezvous' parameter to the InternalURLs entries to make sure the old volume identifiers line up with the new config. If you don't do this, @keep-balance@ will want to shuffle all the existing data around to match the new volume order. The 'Rendezvous' value should be the last 15 characters of the keepstore's UUID in the old configuration. Here's an example:
-
-<notextile>
-<pre><code>Clusters:
- xxxxx:
- Services:
- Keepstore:
- InternalURLs:
- "http://keep1.xxxxx.arvadosapi.com:25107": {Rendezvous: "eim6eefaibesh3i"}
- "http://keep2.xxxxx.arvadosapi.com:25107": {Rendezvous: "yequoodalai7ahg"}
- "http://keep3.xxxxx.arvadosapi.com:25107": {Rendezvous: "eipheho6re1shou"}
- "http://keep4.xxxxx.arvadosapi.com:25107": {Rendezvous: "ahk7chahthae3oo"}
-</code></pre>
-</notextile>
-
-In this example, the keepstore with the name `keep1` had the uuid `xxxxx-bi6l4-eim6eefaibesh3i` in the old configuration.
-
-After migrating and removing all legacy config files, make sure the @/etc/arvados/config.yml@ file is identical across all system nodes -- API server, keepstore, etc. -- and restart all services to make sure they are using the latest configuration.
-
-h2. Cloud installations only: node manager
-
-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. 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@.
+See "Migrating Configuration":https://doc.arvados.org/v2.1/admin/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:
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.

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.

-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.
