Hi List,
oVirt 4.3
I know there have been threads about this before - but I am unable to
find the exact scenario I am facing.
I have a VM with 3 snapshots - Active, and 2 dated ones (technically
created by vProtect)
After trying to do a fresh snapshot in the GUI it failed out and
marked one of the old snapshot disks as 'illegal' - then the other tried
to follow suit.
I tried 'unlocking' the entity using the unlock_entity.sh tool but any
action reverts them back to illegal.
Following previous advice - I can see the VDSM status is all showing
LEGAL:
image: 23710238-07c2-46f3-96c0-9061fe1c3e0d
- *c3dadf14-bb4e-45a7-8bee-b9a01fe29ae1*
*status: OK, voltype: INTERNAL, format: RAW, legality: LEGAL, type:

** status: OK, voltype: INTERNAL, format: COW, legality:

- 4b6f7ca1-b70d-4893-b473-d8d30138bb6b
status: OK, voltype: LEAF, format: COW, legality: LEGAL,
type: SPARSE, capacity: 107374182400, truesize: 12617457664
The 2 bold entries are the 'illegal' snapshots.
Looking in the DB see's:
select
image_guid,parentid
,imagestatus
,vm_snapshot_id
,volume_type
,volume_format
,active
from images
where image_group_id='23710238-07c2-46f3-96c0-9061fe1c3e0d';
image_guid | parentid |
imagestatus | vm_snapshot_id | volume_type | volume_format |
active

So from here previous advice has been to do things such as delete the
snapshot/disk etc but thats when they showed as illegal status. I also
notice the Active Image is not the same image that has a parentid of all
00000's so im not sure on the process of possibly deleting the other
snapshots and disks cleanly and/or safely.
Deleting or any tasks in the gui 100% fails and its at a point that if I
shut down the (critical) VM it will not come back on because of these
status'.
On top of this what is a good way to take a clean, manual backup of
current in use disk before I start playing with this in case worse comes
to worse I have to try build it as a new server (As at this point I
can't trust my vProtect backups)
Any help appreciated.
Thanks,
Joe
