In my case, there where nothing live : the VM was shut down when
creating the snapshot as well as when tyring to delete it.

I understand though live storage migration sub flows are, creation of
live snapshot, so it could be related.



The issue there was fixed after an upgrade to 3.3.1 (as Sander mentioned
it before in the mailing list)

Could you give it a try and check if that works for you?


I'm very shy with upgrading my oVirt production framework, but I began
to read some things to upgrade it. Maybe you can lead me to a precise
way to upgrade vdsm?

Sandro, do you aware of any documentation which can help in upgrading
ovirt, specifically VDSM?


No, I'm not aware of any documentation about it.
However since 3.3.1 is in ovirt-stable if you just need to update vdsm on a 
system I think that

yum  --enablerepo=ovirt-stable update vdsm*


on that system should be enough.


Done


Also it will be great if you could open a bug on that with the full
VDSM, engine logs and the list of lvs.


Done :

https://bugzilla.redhat.com/show_bug.cgi?id=1050901


Just to close the bug :

I updated to 3.4.1-1.el6, and I can not reproduce the bug anymore.

I have to add that in this precise case, recovering the VM is way more 
important than to recover the snapshot, that I can live without.

I've sent two mails altogether - here's the other one:
http://lists.ovirt.org/pipermail/users/2013-November/017557.html.

In December I upgraded to Ovirt 3.3.2. After the upgrade snapshots
works, but I still have a few VMs with broken snapshots. I don't need
these VMs, but I'm keeping them to eventually try to repair them (when
someone helps and tells me how).

[Users] Unable to delete a snapshot

2014-01-06 Thread Nicolas Ecarnot 

Hi,

With our oVirt 3.3, I created a snapshot 3 weeks ago on a VM I've 
properly shutdown.

It ran so far.
Today, after having shut it down properly, I'm trying to delete the 
snapshot and I get an error :


Failed to delete snapshot 'blahblahbla' for VM 'myVM'.

The disk is thin provisionned, accessed via virtIO, nothing special.

The log below comes from the manager.

I hope someone could help us because this server is quite serious.

Thank you.

 Subject: [Users] Unable to delete a snapshot
 
 Hi,
 
 With our oVirt 3.3, I created a snapshot 3 weeks ago on a VM I've
 properly shutdown.
 It ran so far.
 Today, after having shut it down properly, I'm trying to delete the
 snapshot and I get an error :
 
 Failed to delete snapshot 'blahblahbla' for VM 'myVM'.
 
 The disk is thin provisionned, accessed via virtIO, nothing special.
 
 The log below comes from the manager.
 
 I hope someone could help us because this server is quite serious.
 
 Thank you.

Re: [Users] Unable to delete a snapshot

Which subversion of oVirt was this?
And which version of vdsm?
I ran into the same problem with 3.3.0, snapshot deletion was fixed in 3.3.1

Re: [Users] Unable to delete a snapshot

2014-01-06 Thread Maor Lipchuk 
Hi Nicolas,
I think that the initial problem started at 10:06 when VDSM tried to
clear records of the ancestor volume
c50561d9-c3ba-4366-b2bc-49bbfaa4cd23 (see [1])

Looking at bugzilla, it could be related to
https://bugzilla.redhat.com/1029069
(based on the exception described at
https://bugzilla.redhat.com/show_bug.cgi?id=1029069#c1)

The issue there was fixed after an upgrade to 3.3.1 (as Sander mentioned
it before in the mailing list)

Could you give it a try and check if that works for you?

Also it will be great if you could open a bug on that with the full
VDSM, engine logs and the list of lvs.

Regards,
Maor
