# 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][storage-types].
|
|
|
|
## Migrate existing projects to Hashed storage
|
|
|
|
Before migrating your existing projects, you should
|
|
[enable hashed storage][storage-migration] 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**
|
|
|
|
```bash
|
|
sudo gitlab-rake gitlab:storage:migrate_to_hashed
|
|
```
|
|
|
|
**Source Installation**
|
|
|
|
```bash
|
|
sudo -u git -H bundle exec rake gitlab:storage:migrate_to_hashed RAILS_ENV=production
|
|
```
|
|
|
|
They both also accept a range as environment variable:
|
|
|
|
```bash
|
|
# 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][storage-migration] 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:
|
|
|
|
```bash
|
|
sudo gitlab-rake gitlab:storage:rollback_to_legacy
|
|
```
|
|
|
|
For source installations, run the following:
|
|
|
|
```bash
|
|
sudo -u git -H bundle exec rake gitlab:storage:rollback_to_legacy RAILS_ENV=production
|
|
```
|
|
|
|
Both commands accept a range as environment variable:
|
|
|
|
```bash
|
|
# 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.
