Hi Nicolas, I think that the initial problem started at 10:06 when VDSM tried to clear records of the ancestor volume c50561d9-c3ba-4366-b2bc-49bbfaa4cd23 (see [1]) Looking at bugzilla, it could be related to https://bugzilla.redhat.com/1029069 (based on the exception described at https://bugzilla.redhat.com/show_bug.cgi?id=1029069#c1) The issue there was fixed after an upgrade to 3.3.1 (as Sander mentioned it before in the mailing list) Could you give it a try and check if that works for you? Also it will be great if you could open a bug on that with the full VDSM, engine logs and the list of lvs. Regards, Maor [1] 236b3c5a-452a-4614-801a-c30cefbce87e::ERROR::2014-01-06 10:06:14,407::task::850::TaskManager.Task::(_setError) Task=`236b3c5a-452a-4614-801a-c30cefbce87e`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 857, in _run return fn(*args, **kargs) File "/usr/share/vdsm/storage/task.py", line 318, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/share/vdsm/storage/securable.py", line 68, in wrapper return f(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 1937, in mergeSnapshots sdUUID, vmUUID, imgUUID, ancestor, successor, postZero) File "/usr/share/vdsm/storage/image.py", line 1162, in merge srcVol.shrinkToOptimalSize() File "/usr/share/vdsm/storage/blockVolume.py", line 315, in shrinkToOptimalSize volParams = self.getVolumeParams() File "/usr/share/vdsm/storage/volume.py", line 1008, in getVolumeParams volParams['imgUUID'] = self.getImage() File "/usr/share/vdsm/storage/blockVolume.py", line 494, in getImage return self.getVolumeTag(TAG_PREFIX_IMAGE) File "/usr/share/vdsm/storage/blockVolume.py", line 464, in getVolumeTag return _getVolumeTag(self.sdUUID, self.volUUID, tagPrefix) File "/usr/share/vdsm/storage/blockVolume.py", line 662, in _getVolumeTag tags = lvm.getLV(sdUUID, volUUID).tags File "/usr/share/vdsm/storage/lvm.py", line 851, in getLV raise se.LogicalVolumeDoesNotExistError("%s/%s" % (vgName, lvName)) LogicalVolumeDoesNotExistError: Logical volume does not exist: ('11a077c7-658b-49bb-8596-a785109c24c9/_remove_me_aVmPgweS_c50561d9-c3ba-4366-b2bc-49bbfaa4cd23',) On 01/06/2014 04:39 PM, Meital Bourvine wrote:

I don't know why it happens, so you'll have to wait for someone else to answer.

Also, Please attach the whole vdsm.log, it's hard to read it this way (lines are broken)
See attachment.
Actually, I don't know if this mailing list allows attachments ?
