Re: [ovirt-users] Ovirt snapshot failing on one VM

No alert in web ui, I restarted the VM yesterday just in case, no change. I also restored an earlier snapshot and tried to re-snapshot, same result. *Steve * On Tue, Apr 22, 2014 at 10:57 AM, Dafna Ron <dron(a)redhat.com <mailto:dron@redhat.com>> wrote: This is the actual problem: bf025a73-eeeb-4ac5-b8a9-32afa4ae482e::DEBUG::2014-04-22 10:21:49,374::volume::1058::Storage.Misc.excCmd::(createVolume) FAILED: <err> = '/rhev/data-center/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/4 66d9ae9-e46a-46f8-9f4b-964d8af0675b/87efa937-b31f-4bb1-aee1-0ee14a0dc6fb: error while creating qcow2: No such file or directory\n'; <rc> = 1 from that you see the actual failure: bf025a73-eeeb-4ac5-b8a9-32afa4ae482e::ERROR::2014-04-22 10:21:49,392::volume::286::Storage.Volume::(clone) Volume.clone: can't clone: /rhev/data-center/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d 9ae9-e46a-46f8-9f4b-964d8af0675b/1a67de4b-aa1c-4436-baca-ca55726d54d7 to /rhev/data-center/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d9ae9-e46a-46f8-9f4b-964d8af0675b/87efa937-b31f-4bb1-aee1-0ee1 4a0dc6fb bf025a73-eeeb-4ac5-b8a9-32afa4ae482e::ERROR::2014-04-22 10:21:49,392::volume::508::Storage.Volume::(create) Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/volume.py", line 466, in create srcVolUUID, imgPath, volPath) File "/usr/share/vdsm/storage/fileVolume.py", line 160, in _create volParent.clone(imgPath, volUUID, volFormat, preallocate) File "/usr/share/vdsm/storage/volume.py", line 287, in clone raise se.CannotCloneVolume(self.volumePath, dst_path, str(e)) CannotCloneVolume: Cannot clone volume: 'src=/rhev/data-center/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d9ae9-e46a-46f8-9f4b-964d8af0675b/1a67de4b-aa1c-4436-baca-ca55726d54d7, dst=/rhev/data-cen ter/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d9ae9-e46a-46f8-9f4b-964d8af0675b/87efa937-b31f-4bb1-aee1-0ee14a0dc6fb: Error creating a new volume: (["Formatting \'/rhev/data-center/9497ef2c-8368- 4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d9ae9-e46a-46f8-9f4b-964d8af0675b/87efa937-b31f-4bb1-aee1-0ee14a0dc6fb\', fmt=qcow2 size=21474836480 backing_file=\'../466d9ae9-e46a-46f8-9f4b-964d8af0675b/1a67de4b-aa 1c-4436-baca-ca55726d54d7\' backing_fmt=\'qcow2\' encryption=off cluster_size=65536 "],)' do you have any alert in the webadmin to restart the vm?

Please attach full vdsm logs from any host you are using (if you are trying to migrate the vm from host1 to host2) + please attach engine log. Also, what is the vdsm, libvirt and qemu versions, what ovirt version are you using and what is the storage you are using?
