Hello,
after a failed live storage migration (cause unknown) we have a snapshot
which is undeletable due to its status 'illegal' (as seen in
storage/snapshot tab). I have already found some bugs [1],[2],[3]
regarding this issue, but no way how to solve the issue within oVirt 3.5.3.
I have attached the relevant engine.log snippet. Is there any way to do
a live merge (and therefore delete the snapshot)?

Further investigations showed, that the time on the target storage went
backwards due to a misconfigured NTP service. Someone has corrected the
configuration while live storage migration was running and the time
jumped backwards.
Might this be a cause for the issue?

some additional informations. I have checked the images on both storages
and verified the disk paths with virsh's dumpxml.
a) The images and snapshots are on both storages.
b) The images on source storage aren't used. (modification time)
c) The images on target storage are used. (modification time)
d) virsh -r dumpxml tells me disk images are located on _target_ storage.
e) Admin interface tells me, that images and snapshot are located on
_source_ storage, which isn't true, see b), c) and d).
What can we do, to solve this issue? Is this to be corrected in database

Hello,
if no one has an idea how to correct the Disk/Snapshot paths in Engine
database, I see only one possible way to solve the issue:
Stop the VM and copy image/meta files target storage to source storage
(the one where Engine thinks the files are located). Start the VM.
Any concerns regarding this procedure? But I still hope that someone
from oVirt team can give an advice how to correct the database entries.
If necessary I would open a bug in Bugzilla.
Kind regards

got exactly the same issue, with all nice side effects like performance
degradation. Until now i was not able to fix this, or to fool the engine somehow
that it whould show the image as ok again and give me a 2nd chance to drop the
snapshot.
in some cases this procedure helped (needs 2nd storage domain)
-> image live migration to a different storage domain (check which combinations
are supported, iscsi -> nfs domain seems unsupported. iscsi -> iscsi works)
-> snapshot went into ok state, and in ~50% i was able to drop the snapshot
than. space had been reclaimed, so seems like this worked
other workaround is through exporting the image onto a nfs export domain, here
you can tell the engine to not export snapshots. after re-importing everything
is fine
the snapshot feature (live at least) should be avoided at all currently....
simply not reliable enaugh.
your way works, too. already did that, even it was a pita to figure out where to

Hello Juergen,
got exactly the same issue, with all nice side effects like
performance
degradation. Until now i was not able to fix this, or to fool the engine
somehow that it whould show the image as ok again and give me a 2nd
chance to drop the snapshot.
in some cases this procedure helped (needs 2nd storage domain)
-> image live migration to a different storage domain (check which
combinations are supported, iscsi -> nfs domain seems unsupported. iscsi
-> iscsi works)
-> snapshot went into ok state, and in ~50% i was able to drop the
snapshot than. space had been reclaimed, so seems like this worked
okay, seems interesting. But I'm afraid of not knowing which image files
Engine uses when live migration is demanded. If Engine uses the ones
which are actually used and updates the database afterwards -- fine. But
if the images are used that are referenced in Engine database, we will
take a journey into the past.
other workaround is through exporting the image onto a nfs export
domain, here you can tell the engine to not export snapshots. after
re-importing everything is fine
the snapshot feature (live at least) should be avoided at all
currently.... simply not reliable enaugh.
your way works, too. already did that, even it was a pita to figure out

knocking on wood. so far no problems, and i used this way for sure 50 times +
in cases where the live merge failed, offline merging worked in another 50%.
those which fail offline, too went back to illegal snap state

knocking on wood. so far no problems, and i used this way for sure 50

This doesn't work. Engine creates the snapshots on wrong storage (old)
and this process fails, cause the VM (qemu process) uses the images on
other storage (new).
in cases where the live merge failed, offline merging worked in
another
50%. those which fail offline, too went back to illegal snap state
I fear offline merge would cause data corruption. Because if I shut down
the VM, the information in Engine database is still wrong. Engine thinks
image files and snapshots are on old storage. But VM has written to the
equal named image files on new storage. And offline merge might use the
"old" files on old storage.

Same issue as with offline merge.
Meanwhile I think, we need to shut down the VM, copy the image files
from one storage (qemu has used before) to the other storage (the one
Engine expects) and pray while starting the VM again.

sounds like there are some other problems in your case, wrong db entries
image -> snapshot? i didnt investigate further in the vm which failed
this process, i directly went further and exported them
Yes, engine thinks image and snapshot are on storage a, but qemu process
uses equal named images on storage b.
It seems to me, that first live storage migration was successful on qemu
level, but engine hasn't updated the database entries.
Seems to be a possible solution to correct the database entries, but I'm
not familar with the oVirt schema and won't even try it without an
advice from oVirt developers.

than your initial plan is an alternative. you use thin or raw on what
kind of storage domain? but like said, manually processing is a pita due
to the symlink mess.
We are using raw images which are thin provisioned on NFS based storage
domains. On storage b I can see an qcow formatted image file which qemu
uses and the original (raw) image which is now backing file.

Yes, engine thinks image and snapshot are on storage a, but qemu process
uses equal named images on storage b.
It seems to me, that first live storage migration was successful on qemu
level, but engine hasn't updated the database entries.
Seems to be a possible solution to correct the database entries, but I'm
not familar with the oVirt schema and won't even try it without an
advice from oVirt developers.

We are using raw images which are thin provisioned on NFS based storage
domains. On storage b I can see an qcow formatted image file which qemu
uses and the original (raw) image which is now backing file.
might sound a little bit curious, but imho this is the best setup for your plan.
thin on iscsi is an totally different story... lvm volumes which get extended on
demand (which fails with default settings during heavy writes, and causes vm to
pause), additionally ovirt writes qcows images raw onto those lv volumes. since
you can get your hands directly on the images this whould be my prefered
workaround. but maybe one of the ovirt devs got a better idea/solution?
