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.
Upgrade instructions can be found at Maintenance and upgrading.
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. These notes are listed below, organized by release version. Scroll down to the version number you are upgrading to.
There are no changes requiring special attention in this version.
There are no changes requiring special attention in this version.
If you use LSF and your configuration specifies Containers.LSF.BsubArgumentsList, you should update it to include the new arguments ("-R", "select[mem>=%MMB]", ..., see configuration reference). Otherwise, containers that are too big to run on any LSF host will remain in the LSF queue instead of being cancelled.
Due to a bug in previous versions, the DELETE operation on a role group caused the group to be flagged as trash in the database, but continue to grant permissions regardless. After upgrading, any role groups that had been trashed this way will be deleted. This might surprise some users if they were relying on permissions that were still in effect due to this bug. Future DELETE operations on a role group will immediately delete the group and revoke the associated permissions.
When a new user is set up (either via AutoSetupNewUsers config or via Workbench admin interface) the user immediately becomes visible to other users. To revert to the previous behavior, where the administrator must add two users to the same group using the Workbench admin interface in order for the users to see each other, change the new Users.ActivatedUsersAreVisibleToOthers config to false.
If your installation uses the vocabulary feature on Workbench2, you will need to update the cluster configuration by moving the vocabulary definition file to the node where controller runs, and set the API.VocabularyPath configuration parameter to the local path where the file was placed.
This will enable the vocabulary checking cluster-wide, including Workbench2. The Workbench.VocabularyURL configuration parameter is deprecated and will be removed in a future release.
You can read more about how this feature works on the admin page.
Ubuntu 18.04 ships with Bundler version 1.16.1, which is no longer compatible with the Gemfiles in the Arvados packages (made with Bundler 2.2.19). The Ubuntu 18.04 packages for arvados-api-server and arvados-workbench now conflict with the ruby-bundler package to work around this issue. The post-install scripts for arvados-api-server and arvados-workbench install the proper version of Bundler as a gem.
update_uuid endpoint for users.The update_uuid endpoint was superseded by the link accounts feature, so it’s no longer available.
The ‘@@’ full text search operator, previously deprecated, has been removed. To perform a string search across multiple columns, use the ‘ilike’ operator on ‘any’ column as described in the available list method filter section of the API documentation.
If your configuration uses the StorageClasses attribute on any Keep volumes, you must add a new StorageClasses section that lists all of your storage classes. Refer to the updated documentation about configuring storage classes for details.
Make sure the keep-balance process can connect to your PostgreSQL server using the settings in your config file. (In previous versions, keep-balance accessed the database through controller instead of connecting to the database server directly.)
The crunch-dispatch-local dispatcher now reads the API host and token from the system wide /etc/arvados/config.yml . It will fail to start that file is not found or not readable.
Typically a docker image collection contains a single .tar file at the top level. Handling of atypical cases has changed. If a docker image collection contains files with extensions other than .tar, they will be ignored (previously they could cause errors). If a docker image collection contains multiple .tar files, it will cause an error at runtime, “cannot choose from multiple tar files in image collection” (previously one of the .tar files was selected). Subdirectories are ignored. The arv keep docker command always creates a collection with a single .tar file, and never uses subdirectories, so this change will not affect most users.
If you use the S3 driver for Keep volumes and specify credentials in your configuration file (as opposed to using an IAM role), you should change the spelling of the AccessKey and SecretKey config keys to AccessKeyID and SecretAccessKey. If you don’t update them, the previous spellings will still be accepted, but warnings will be logged at server startup.
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 for an example) and reload/restart Nginx (sudo nginx -s reload).
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
preserve_version attribute semanticsThe 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.
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.
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.
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.
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.
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:
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
On CentOS:
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
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 for more information.
The Python-based PAM package has been replaced with a version written in Go. See using PAM for authentication for details.
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 for details.
After migrating your configuration, uninstall the arvados-sso-provider package.
Keepstore now uses V4 signatures 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.
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.
group_class field must be either role or project. Invalid group_class are migrated to role.role cannot own things. Anything owned by a role is migrated to a can_manage link and reassigned to the system user.role and user can have outgoing permission links. Permission links originating from projects are deleted by the migration.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.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):
arv group list --filters '[["group_class", "not in", ["project", "role"]]]'
To list all role groups, which will be reassigned to the system user (unless owner_uuid is already the system user):
arv group list --filters '[["group_class", "=", "role"]]'
To list which project groups have outgoing permission links (such links are now invalid and will be deleted by the migration):
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
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.
Arvados 2.0 is a major upgrade, with many changes. Please read these upgrade notes carefully before you begin.
See Migrating Configuration 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:
Clusters:
zzzzz:
Services:
Controller:
ExternalURL: "https://zzzzz.example.com"
(feature #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 and keep-balance install guide for more details.
(feature #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 for more details.
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 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 and keepstore install guide for more details.
(feature #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 for more details.
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.
$ export ARVADOS_API_HOST=...
$ export ARVADOS_API_TOKEN=...
$ arv --format=uuid keep_service list | xargs -n1 arv keep_service delete --uuid
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.
Feature #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 CREATE EXTENSION pg_trgm SQL command on the arvados_production database as a postgres superuser.
The postgres-contrib package 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:
Centos 7
~$ sudo yum install -y postgresql95-contrib
~$ su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"
RHEL 7
~$ sudo yum install -y rh-postgresql95-postgresql-contrib
~$ su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"
Debian or Ubuntu
~$ sudo apt-get install -y postgresql-contrib-9.5
~$ sudo -u postgres psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'
Subsequently, the psql -d 'arvados_production' -c '\dx' command will display the installed extensions for the arvados_production database. This list should now contain pg_trgm.
Workbench 2 is now ready for regular use. Follow the instructions to install workbench 2
(feature #14151) Workbench2 supports a new vocabulary format and it isn’t compatible with the previous one, please read the metadata vocabulary format admin page for more information.
Node manager is deprecated and replaced by arvados-dispatch-cloud. No automated config migration is available. Follow the instructions to install the cloud dispatcher
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.
~$ sudo systemctl --now disable crunch-dispatch-slurm
~$ sudo apt-get remove crunch-dispatch-slurm
(task #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.
(issue #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.
(bug #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.
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.
The Python 3 dependency for Centos7 Arvados packages was upgraded from rh-python35 to rh-python36.
As part of story #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 populate-file-info-columns-in-collections.rb 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.
As a consequence of #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:
~$ rvm gemset create rubysdk-test
~$ rvm gemset use rubysdk-test
~$ gem install arvados -v 1.3.1.20190301212059
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:
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
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.
As part of story #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 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:
~$source /usr/share/python2.7/dist/python-arvados-python-client/bin/activate(python-arvados-python-client) ~$path-to-the-python-script
Or alternatively, by updating the shebang line at the start of the script to:
#!/usr/share/python2.7/dist/python-arvados-python-client/bin/python
As part of story #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.
As part of story #9945, the Python 3 dependency for Centos7 Arvados packages was upgraded from SCL python33 to rh-python35.
As part of story #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.
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 for details.
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 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 which can be used to identify the workflows that generated those collections and who ran those workflows, so that they can be rerun.
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 as support for the “jobs” API will be dropped in an upcoming release. Users who are already using the “containers” API are not affected.
There are no special upgrade notes for this release.
previous: Upgrading to 1.1.2 or 1.1.3
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:
#!/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
If you also need to do the vacuum, you could adapt the script to run ‘vacuum analyze’ instead of ‘analyze’.
Commit db5107dca adds a new system service, arvados-controller. More detail is available in story #13496.
To add the Arvados Controller to your system please refer to the installation instructions 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.
Secondary files missing from toplevel workflow inputs
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:
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
When run, this produces an error like this:
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": []
}
To fix this error, add the appropriate secondaryFiles section to toplevel_input
class: Workflow
cwlVersion: v1.0
inputs:
toplevel_input:
type: File
secondaryFiles:
- .idx
outputs: []
steps:
step1:
in:
step_input: toplevel_input
out: []
run:
id: sub
class: CommandLineTool
inputs:
step_input:
type: File
secondaryFiles:
- .idx
outputs: []
baseCommand: echo
This bug has been fixed in Arvados release v1.2.0.
Secondary files on default file inputs
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:
class: CommandLineTool
inputs:
step_input:
type: File
secondaryFiles:
- .idx
default:
class: File
location: hello.txt
outputs: []
baseCommand: echo
When run, this produces an error like this:
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'
To fix this, manually upload the primary and secondary files to keep and explicitly declare secondaryFiles on the default primary file:
class: CommandLineTool
inputs:
step_input:
type: File
secondaryFiles:
- .idx
default:
class: File
location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt
secondaryFiles:
- class: File
location: keep:4d8a70b1e63b2aad6984e40e338e2373+69/hello.txt.idx
outputs: []
baseCommand: echo
This bug has been fixed in Arvados release v1.2.0.
