Check if the cleanup has umounted the volume bricks.
If they are still mounted, you can use a backup of the system to retrieve the definition of the gluster volumes (/var/lib/gluster). Once you copy the volume dir, stop glusterd (this is just management layer) on all nodes and then start them one by one. Keep in mind that nodes to sync between each other , so restarting the nodes 1 by 1 is useless.

You can also try to create the volume (keep the name) on the sane bricks via the force flag and just hope it will have the data in the bricks (never done that).

hi everyone,

I have a 3x node ovirt 4.4.6 cluster in HC setup.

Today I was intending to extend the data and vmstore volume adding another brick each; then by accident I pressed the "cleanup" button. Basically it looks that the volume were deleted.

I am wondering whether there is a process of trying to recover these volumes and therefore all VMs (including the Hosted-Engine).

I would appreciate any advice.
