[ovirt-users] Re: Locked disks

In such a case, the disks shouldn't remain locked - sounds like a bug. This one requires a deeper look. If you're able to reproduce it again, please open a bug in Bugzilla (https://bugzilla.redhat.com <https://bugzilla.redhat.com>) with engine and vdsm logs, so we'll be able to investigate it. *Regards, * *Shani Leviim * On Wed, Feb 3, 2021 at 5:39 PM Giulio Casella <giulio(a)di.unimi.it <mailto:giulio@di.unimi.it>> wrote: Hi, I tried unlock_entity.sh, and it solved the issue. So far so good. But it's still unclear why disks were locked. Let me make an hypothesis: in ovirt 4.3 a failure in snapshot removal would lead to a snapshot in illegal status. No problem, you can remove again and the situation is fixed. In ovirt 4.4 a failure in snapshot removal leave the whole disk in locked state (maybe a bug?), preventing any further action. Does it make sense?
