[ovirt-users] critical production issue for a vm

[Nathanaël Blanchet]

Hi all,

I'm about to lose one very important vm. I shut down this vm for 
maintenance and then I moved the four disks to a new created lun. This 
vm has 2 snapshots.

After successful move, the vm refuses to start with this message:

Bad volume specification {u'index': 0, u'domainID': 
u'961ea94a-aced-4dd0-a9f0-266ce1810177', 'reqsize': '0', u'format': 
u'cow', u'bootOrder': u'1', u'discard': False, u'volumeID': 
u'a0b6d5cb-db1e-4c25-aaaf-1bbee142c60b', 'apparentsize': '2147483648', 
u'imageID': u'4a95614e-bf1d-407c-aa72-2df414abcb7a', u'specParams': {}, 
u'readonly': u'false', u'iface': u'virtio', u'optional': u'false', 
u'deviceId': u'4a95614e-bf1d-407c-aa72-2df414abcb7a', 'truesize': 
'2147483648', u'poolID': u'48ca3019-9dbf-4ef3-98e9-08105d396350', 
u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off', 
u'type': u'disk'}.

I tried to merge the snaphots, export , clone from snapshot, copy disks, 
or deactivate disks and every action fails when it is about disk.

I began to dd lv group to get a new vm intended to a standalone 
libvirt/kvm, the vm quite boots up but it is an outdated version before 
the first snapshot. There is a lot of disks when doing a "lvs | grep 
961ea94a" supposed to be disks snapshots. Which of them must I choose to 
get the last vm before shutting down? I'm not used to deal snapshot with 
virsh/libvirt, so some help will be much appreciated.

Is there some unknown command to recover this vm into ovirt?

Thank you in advance.
