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

[Jan Siml]

Hello,

some additional informations. I have checked the images on both storages 
and verified the disk paths with virsh's dumpxml.

a) The images and snapshots are on both storages.
b) The images on source storage aren't used. (modification time)
c) The images on target storage are used. (modification time)
d) virsh -r dumpxml tells me disk images are located on _target_ storage.
e) Admin interface tells me, that images and snapshot are located on 
_source_ storage, which isn't true, see b), c) and d).

What can we do, to solve this issue? Is this to be corrected in database 
only?

Kind regards
