[PVE-User] Cannot delete snapshot from aborted snapshot creation process

[Frank Thommen]

Hi,

I aborted the creation of a snapshot (started and stopped through web 
UI, PROXMOX version is 7.3-3). No I cannot delete this snapshot any more:

# qm unlock 118
# qm delsnapshot 118 pre_db_migration_to_postgres
VM 118 qmp command 'blockdev-snapshot-delete-internal-sync' failed - 
Snapshot with id 'null' and name 'pre_db_migration_to_postgres' does not 
exist on device 'drive-scsi0'
#

but the snapshot /is/ listed:

# qm listsnapshot 118
`-> pre_db_migration_to_postgres 2023-03-30 17:58:38     no-description
`-> current                                             You are here!
#


Similar errors appear when trying it through the web UI. I tried this 
several times (UI and CLI). I attach a screenshot of how the snapshot 
presents itself in the web UI


I must add, that while I created the snapshot (and aborted the process), 
the VM was in HA-mode. I took it out of HA after the first few tries to 
delete the snapshot, to avoid, that this is a HA side effect.

Also while starting the the snapshot creation, the VM was running, but 
it was off once I had aborted the process and checked the VM status.


Any idea, how I can get rid of this snapshot (or the snapshot being 
listed, in case this is just a ghost entry)?
