[ovirt-users] Re: Snapshot error with Cinder/Ceph disk

Hi, i'm having problems with snapshotting Cinder/Ceph disks since upgrading to 4.2. Observed behavior has changed between 4.2.2 and 4.2.4. With oVirt 4.2.2 and Cinder 11.1.0 - oVirt snapshot fails (according to oVirt), but is listed in GUI - disk snapshot are visible in oVirt storage domain tab and Cinder CLI - first try to remove the oVirt snapshot fails (according to oVirt), but disk snapshots are removed from oVirt storage domain tab and Cinder CLI - second try to remove oVirt snapshot succeeds With oVirt 4.2.4 and Cinder 11.1.1 - oVirt snapshot fails "completely" - in Cinder logs i can see that disk snapshots are created and immediately deleted oVirt error log message is the same in both cases: "Failed in 'SnapshotVDS' method" I'm attaching logs from oVirt engine from the latter case. thx for any advice matthias
