Multiple deployments writing to the same snapshot repository

edit

Multiple Elasticsearch deployments are writing to the same snapshot repository. Elasticsearch doesn’t support this configuration and only one cluster is allowed to write to the same repository. To remedy the situation mark the repository as read-only or remove it from all the other deployments, and re-add (recreate) the repository in the current deployment:

Fixing the corrupted repository will entail making changes in multiple deployments that write to the same snapshot repository. Only one deployment must be writing to a repository. The deployment that will keep writing to the repository will be called the "primary" deployment (the current cluster), and the other one(s) where we’ll mark the repository read-only as the "secondary" deployments.

First mark the repository as read-only on the secondary deployments:

Use Kibana

  1. Log in to the Elastic Cloud console.
  2. On the Elasticsearch Service panel, click the name of your deployment.

    If the name of your deployment is disabled your Kibana instances might be unhealthy, in which case please contact Elastic Support. If your deployment doesn’t include Kibana, all you need to do is enable it first.

  3. Open your deployment’s side navigation menu (placed under the Elastic logo in the upper left corner) and go to Stack Management > Snapshot and Restore > Repositories.

    Kibana Console
  4. The repositories table should now be visible. Click on the pencil icon at the right side of the repository to be marked as read-only. On the Edit page that opened scroll down and check "Read-only repository". Click "Save". Alternatively if deleting the repository altogether is preferable, select the checkbox at the left of the repository name in the repositories table and click the "Remove repository" red button at the top left of the table.

At this point, it’s only the primary (current) deployment that has the repository marked as writeable. Elasticsearch sees it as corrupt, so the repository needs to be removed and added back so that Elasticsearch can resume using it:

Note that we’re now configuring the primary (current) deployment.

  1. Open the primary deployment’s side navigation menu (placed under the Elastic logo in the upper left corner) and go to Stack Management > Snapshot and Restore > Repositories.

    Kibana Console
  2. Click on the pencil icon at the right side of the repository. On the Edit page that opened scroll down and click "Save", without making any changes to the existing settings.
