Deleting Snapshot failed
Hello everybody, last night my backup script was not able to finish the backup from a VM in the last step of deleting the snapshot. And now I also can not delete this snapshot by hand, the message says: VDSM onode2 command MergeVDS failed: Drive image file could not be found: {'driveSpec': {'poolID': 'c9baa5d4-3543-11eb-9c0c-00163e33f845', 'volumeID': '024e1844-c19b-40d8-a2ac-cb4ea6ec34e6', 'imageID': 'ad23c0db-1838-4f1f-811b-2b213d3a11cd', 'domainID': '3cf83851-1cc8-4f97-8960-08a60b9e25db'}, 'job': '96c7003f-e111-4270-b922-d9b215aaaea2', 'reason': 'Cannot find drive'} The full log you found in the attachment. Any idea? Best regard Jonathan
Sounds to me as though it has completed the disk delete underneath but it has remained in the database. I've had similar issues with it also locking the images on the VM and making me worried it can not be started up should it shut down. Unfortunately the best fix I've found on a production kit is to try and simply restore from latest backups as a new VM and delete the old one. I managed in one or 2 cases to 'clone' the VM to create the new one. The other solution 'may' be to just delete it from the database, how to do so cleanly im not sure, but you'd also have to make sure the disk chain etc is in-tact and matches what is now in the engine database. It gets really messy really quickly when this kind of thing happens and has caused me a good amount of stress before :P ------ Original Message ------ From: "Jonathan Baecker" <jonbae77@gmail.com> To: "users" <users@ovirt.org> Sent: 27/02/2022 5:53:38 AM Subject: [ovirt-users] Deleting Snapshot failed

There are threads to verify the disk chain and how to cleanup the db entry .

I though that to, but I think is more. When I run: vdsm-tool dump-volume-chains "sd_id" I get: image: ad23c0db-1838-4f1f-811b-2b213d3a11cd - 15259a3b-1065-4fb7-bc3c-04c5f4e14479 status: OK, voltype: INTERNAL, format: COW, legality: LEGAL, type: SPARSE, capacity: 21474836480, truesize: 6279929856 - 024e1844-c19b-40d8-a2ac-cb4ea6ec34e6 status: OK, voltype: LEAF, format: COW, legality: ILLEGAL, type: SPARSE, capacity: 21474836480, truesize: 1302528 15259a3b-1065-4fb7-bc3c-04c5f4e14479 is the snapshot.
