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
