Hi,
Did you try to remove the same snapshot while the VM is down?

Hi Benny,
I used the tool to track one of the illegal volumes:
image: e05874d2-fb8a-4fd2-94ff-2f4bc6438d47
[...]
- 887f486b-15cf-4083-9b35-8b7821a7841a
status: ILLEGAL, voltype: LEAF, format: COW,
legality: ILLEGAL, type: SPARSE
So I tracked 887f486b-15cf-4083-9b35-8b7821a7841a in the logs and I
saw:

Can you provide some additional steps?
Thank you!

We prevent starting VMs with illegal images[1]
You can use "$ vdsm-tool dump-volume-chains"
to look for illegal images and then look in the engine log for the
reason they became illagal,
if it's something like this, it usually means you can remove them:

Indeed, when the problem started I think the SPM was the host I
added as VDSM log in the first e-mail. Currently it is the one I
sent in the second mail.
FWIW, if it helps to debug more fluently, we can provide VPN access
to our infrastructure so you can access and see whateve you need
(all hosts, DB, etc...).
Right now the machines that keep running work, but once shut down
they start showing the problem below...
Thank you

I'm having trouble following the errors, I think the SPM changed or
the vdsm log from the right host might be missing.
However, I believe what started the problems is this transaction

This looks like a bug
Regardless, I am not sure restoring a backup would help since you
probably have orphaned images on the storage which need to be
removed

Hi,
We're running oVirt 4.1.9 (we cannot upgrade at this time) and
we're having a major problem in our infrastructure. On friday, a
snapshots were automatically created on more than 200 VMs and as
this was just a test task, all of them were deleted at the same
time, which seems to have corrupted several VMs.
When trying to delete a snapshot on some of the VMs, a "General
error" is thrown with a NullPointerException in the engine log
(attached).
But the worst part is that when some of these machines is powered
off and then powered on, the VMs are corrupt...

We're really frustrated by now and don't know how to procceed... We
have a DB backup (with engine-backup) from thursday which would
have
a "sane" DB definition without all the snapshots, as they were all
created on friday. Would it be safe to restore this backup?
Any help is really appreciated...
Thanks.
