[ovirt-users] Delete snapshot with status illegal - live merge not possible

[Jan Siml]

Hello,

after a failed live storage migration (cause unknown) we have a snapshot 
which is undeletable due to its status 'illegal' (as seen in 
storage/snapshot tab). I have already found some bugs [1],[2],[3] 
regarding this issue, but no way how to solve the issue within oVirt 3.5.3.

I have attached the relevant engine.log snippet. Is there any way to do 
a live merge (and therefore delete the snapshot)?

Kind regards
