Re: [Users] Unable to delete a snapshot

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:
