Hi Nir, in bugzilla I see it could be a bug, so I'm waiting for software update to fix it. In the meanwhile is there some fix I can do on the database? The VM is working fine, but I cannot operate with snapshots, and my backup is stuck... TIA, Giulio Casella On 12/04/2021 16:54, Giulio Casella wrote:

Hi, I'm having (another) issue working with snapshots.
Since a few days my backup system (storware vprotect) cannot delete a snapshot. Message reported by SPM is:
HSMGetAllTasksStatusesVDS failed: value=Volume does not exist: ('6180c2e8-141a-4126-bcb1-5af5caa98175',) abortedcode=201
Other snapshots from other VMs are working fine (created and deleted as needed).
I verified it, I can reach on SPM filesystem other snapshots from the same VM, but that one doesn't exist.
I suspect that during normal backup management that snapshot has been correctly removed from file system, but still live in ovirt database.
I'm pretty sure vProtect use ovirt API to operate, it doesn't directly interact with ovirt database. That's why I'm talking to you and not to storware guys.
Is there a (safe) way to get rid of that snapshot?
If the snapshot was already removed, ovirt should detect this and complete the operation successfully.
Please file ovirt bug for this, and attach engine and vdsm logs showing the effected snapshot and disk snapshot id.
You can get find the snapshot id is the UI. You can see the disk snapshot id in vm > snapshots > disks > disk id
Then grep engine and vdsm log for the disk id an attach all the logs mentioning this disk id.
It will be also useful to get a database dump so we can see what engine knows about this snapshot.
Benny, can you recommend some queries to extract relevant info?
Nir
