Repository Storage Rake Tasks
This is a collection of rake tasks you can use to help you list and migrate existing projects and attachments associated with it from Legacy storage to the new Hashed storage type.
You can read more about the storage types here.
Migrate existing projects to Hashed storage
Before migrating your existing projects, you should enable hashed storage for the new projects as well.
This task will schedule all your existing projects and attachments associated with it to be migrated to the Hashed storage type:
Omnibus Installation
sudo gitlab-rake gitlab:storage:migrate_to_hashed
Source Installation
sudo -u git -H bundle exec rake gitlab:storage:migrate_to_hashed RAILS_ENV=production
They both also accept a range as environment variable:
# to migrate any non migrated project from ID 20 to 50.
export ID_FROM=20
export ID_TO=50
You can monitor the progress in the Admin Area > Monitoring > Background Jobs page.
There is a specific Queue you can watch to see how long it will take to finish:
hashed_storage:hashed_storage_project_migrate
After it reaches zero, you can confirm every project has been migrated by running the commands bellow. If you find it necessary, you can run this migration script again to schedule missing projects.
Any error or warning will be logged in Sidekiq's log file.
NOTE: Note: If Geo is enabled, each project that is successfully migrated generates an event to replicate the changes on any secondary nodes.
You only need the gitlab:storage:migrate_to_hashed rake task to migrate your repositories, but we have additional
commands below that helps you inspect projects and attachments in both legacy and hashed storage.
Rollback from Hashed storage to Legacy storage
If you need to rollback the storage migration for any reason, you can follow the steps described here.
NOTE: Note: Hashed Storage will be required in future version of GitLab.
To prevent new projects from being created in the Hashed storage, you need to undo the enable hashed storage changes.
This task will schedule all your existing projects and associated attachments to be rolled back to the Legacy storage type.
For Omnibus installations, run the following:
sudo gitlab-rake gitlab:storage:rollback_to_legacy
For source installations, run the following:
sudo -u git -H bundle exec rake gitlab:storage:rollback_to_legacy RAILS_ENV=production
Both commands accept a range as environment variable:
# to rollback any migrated project from ID 20 to 50.
export ID_FROM=20
export ID_TO=50
You can monitor the progress in the Admin Area > Monitoring > Background Jobs page.
On the Queues tab, you can watch the hashed_storage:hashed_storage_project_rollback queue to see how long the process will take to finish.
After it reaches zero, you can confirm every project has been rolled back by running the commands bellow. If some projects weren't rolled back, you can run this rollback script again to schedule further rollbacks.
Any error or warning will be logged in Sidekiq's log file.
