The vdsm logs are not the correct ones. I assume this is the failure: 2020-02-04 22:04:53,631+05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.MergeVDSCommand] (EE-ManagedThreadFactory-commandCoordinator-Thread-9) [1e9f5492-095c-48ed-9aa0-1a899eedeab7] Command 'MergeVDSCommand(HostName = iondelsvr72.iontrading.com, MergeVDSCommandParameters:{hostId='22502af7-f157-40dc-bd5c-6611951be729', vmId='4957c5d4-ca5e-4db7-8c78-ae8f4b694646', storagePoolId='c5e0f32e-0131-11ea-a48f-00163e0fe800', storageDomainId='70edd0ef-e4ec-4bc5-af66-f7fb9c4eb419', imageGroupId='737b5628-e9fe-42ec-9bce-38db80981107', imageId='31c5e807-91f1-4f73-8a60-f97a83c6f471', baseImageId='e4160ffe-2734-4305-8bf9-a7217f3049b6', topImageId='31c5e807-91f1-4f73-8a60-f97a83c6f471', bandwidth='0'})' execution failed: VDSGenericException: VDSErrorException: Failed to MergeVDS, error = Drive image file could not be found, code = 13 please find the vdsm logs containing flow_id 1e9f5492-095c-48ed-9aa0-1a899eedeab7 and provide output for `vdsm-tool dump-volume-chains 70edd0ef-e4ec-4bc5-af66-f7fb9c4eb419` so we can see the status of the chain on vdsm As well as `virsh -r dumpxml ind-co-ora-ee-02` (assuming ind-co-ora-ee-02 is the VM with the issue) Changing the snapshot status with unlock_entity will likely work only if the chain is fine on the storage On Tue, Feb 4, 2020 at 7:40 PM Crazy Ayansh <shashank123rastogi@gmail.com> wrote:

back to my question then, can you check what made the snapshot illegal? and attach the vdsm and engine logs from the occurrence so we can assess the damage

also run `dump-volume-chains <sd_id>` where the image resides so we can see what's the status of the image on vdsm

Is the VM running? Can you remove it when the VM is down? Can you find the reason for illegal status in the logs?
