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:

The 2 bold entries are the 'illegal' snapshots.
Looking in the DB see's:

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

Hi
We have the same issue as you, and we are also using vProtect.
I have no solution, but I'm very interested in how to address this.
Some VM:s we do have managed to remove the illegal snapshots after changing storage for
the VM:s disks, but we have 3-4 VM:s that will not want to remove the illegal snapshot.
As for us, this issue has escalated the last couple of months.
Is it only us who have these issues or does people not take backup of their VM:s? Feels
like more people should have these issues.
//Magnus

Do you know why your snapshot creation failed? Do you have logs with the error?
On paper the situation does not look too bad, as the only discrepancy
between the database and vdsm is the status of the image, and since
it's legal on vdsm, changing it legal in database should work (image
status 1)
Active Image is not the same image that has a parentid of all 00000
Can you elaborate on this? The image with the empty parent is usually
the base image (the first active image), the active image will usually
be the leaf (unless the VM is in preview or something similar)
Of course do not make any changes without backing up first

Can you elaborate on this? The image with the empty parent is usually
the base image (the first active image), the active image will usually
be the leaf (unless the VM is in preview or something similar)
This is probably
just my misunderstanding of the snapshot structure.
Of course do not make any changes without backing up first
Whats the best way to back up this (running) VM without snapshots? Can I
just copy the folder and disk? Is there a way to copy it so it doesn't
copy it as a 100G file (when only 20G used)?

The UUID's match the UUID's in the snapshot list.
So much stuff happens in vdsm.log its hard to pinpoint whats going on
but grepping 'c149117a-1080-424c-85d8-3de2103ac4ae' (flow-id) shows
pretty much those 2 calls and then XML dump.
Still a bit lost on the most comfortable way forward unfortunately.

Attached XML dump.
Looks like its let me run a 'reboot' but im afraid to do a shutdown at
this point.
I have taken just a raw copy of the whole image group folder in the hope
if worse came to worse I'd be able to recreate the disk with the actual
files.
All existing files seem to be referenced in the xmldump.
