[ovirt-devel] Re: RHV and oVirt CBT issue

Dear all, FYI, after upgrading oVirt engine to 4.4.7.7-1.el8 the chance of reproducing this issue is reduced, but it still persists.

The oVirt node version is also 4.4.7, the virtual disks are stored in iSCSI LUN. The problem occurred yesterday, but we waited for more than 20 hours, still 2 disks and in Finalizing state. At this moment, we are unable to check/delete snapshots, or perform backups. Please let us know if we can do anything to help with the debug. Thanks & regards!
