HI,
OK, how to properly remove this lock? Right now VM is locked and is unmanageable at all in
any way.
I suppose its with some SQL commands in Postgres.
Thanks.

So based on your logs the lock you are seeing is a memory lock,
unlock_entity.sh can't really help with these.
Also, the job table is used mainly for presentation so removing an
entry from will not help.
Do you have the logs from when this snapshot operation started, you
can use the correlation id (28353fa0-5e36-4fe8-8609-e74cd1da6d36) to
search? Also, do you have the vdsm logs (SPM at the time and the host
running the VM), same correlation id can be used for this as well
The table that's used to coordinate this is command_entities, so in
theory removing the entries with this correlation id can help, but I'd
like to see what led to this first
