How to restore volume from snapshot on CODE-DE

In this article, you will learn how to restore volume from volume snapshot using Horizon dashboard or OpenStack CLI client.

This can be achieved by creating a new volume from existing snapshot. You can then delete the previous snapshot and, optionally, previous volume.

Prerequisites

No. 1 Hosting

You need a CODE-DE hosting account with access to Horizon interface: https://cloud.fra1-1.cloudferro.com/auth/login/?next=/

No. 2 A volume snapshot

You need to have a volume snapshot which you want to restore.

No. 3 OpenStack CLI client

If you want to interact with CODE-DE cloud using the OpenStack CLI client, you need to have it installed. Check one of these articles:

Once you have installed this piece of software, you need to authenticate to start using it: So aktivieren Sie den OpenStack-CLI-Zugriff auf die CODE-DE-Cloud mit Ein- oder Zwei-Faktor-Authentifizierung

Restoring volume snapshot using Horizon dashboard

Navigate to the Volumes -> Snapshots section of the Horizon dashboard:

../_images/how-to-restore-volume-from-snapshot-Horizon-01_creodias.png

From the row representing the snapshot you want to restore, in the Actions column choose Create Volume:

../_images/how-to-restore-volume-from-snapshot-Horizon-02_creodias.png

You should get the window similar to this:

../_images/how-to-restore-volume-from-snapshot-Horizon-03_creodias.png

If you want your new volume to have a different name than your snapshot, enter the name of your choice in text field Volume Name.

In this example, we will name our new volume my-restored-volume.

Click Create Volume.

You should now be transferred to section Volumes -> Volumes of the Horizon dashboard. Your newly created volume should be there (in this example, its name was marked with a blue rectangle):

../_images/how-to-restore-volume-from-snapshot-Horizon-04_creodias.png

Make sure that the volume has the following Status: Available.

Restoring volume snapshot using OpenStack CLI client

Execute the following command:

openstack volume snapshot list

You should see the list of snapshots of your volumes:

../_images/how-to-restore-volume-from-snapshot-cli-01_creodias.png

Write somewhere down the ID of the snapshot from which you want to create a volume:

In this example, we want to restore the snapshot called my-snapshot. Its ID, marked on screenshot above with a blue rectangle, is d0f384be-3e61-49a4-8742-70929d22032e

To create a volume from your snapshot, execute command below, after replacing values as instructed.

openstack volume create --snapshot d0f384be-3e61-49a4-8742-70929d22032e my-restored-volume

Replace:

  • d0f384be-3e61-49a4-8742-70929d22032e with the ID of your volume snapshot

  • my-restored-volume with the name you want to give to your new volume

You should get output similar to this:

../_images/how-to-restore-volume-from-snapshot-cli-02_creodias.png

List volumes:

openstack volume list

Your new volume should now be on the list:

../_images/how-to-restore-volume-from-snapshot-cli-03_creodias.png

Make sure that newly created volume has the following Status: available.

What To Do Next

You can now connect your new volume to a virtual machine and/or delete the previous one.
