sanlock.log on the second host (ovirt002) doesn't have any entries anywhere near that time of failure.I see some heal-failed errors in gluster, but seeing as the storage is exposed via NFS I'm surprised to think this might be the issue. I'm working on fixing those files now, I'll update if I make any progress.

Elad, can you please try to reproduce this?
gluster storage -> at least two vm's server type created from template as thin provision (it's clone copy).
after create run and migrate all vm's from one host to the second host.
I think it would be a locking issue.
Steve, can you please also check the sanlock log in the second host + look if there are any errors in the gluster logs (on both hosts)?
Thanks,
Dafna

VM's are identical, same template, same cpu/mem/nic. Server type, thin provisioned on NFS (backend is glusterfs 3.4).
Does monitor = spice console? I don't believe either of them had a spice connection.
I don't see anything in the ovirt001 sanlock.log:

ovirt002 sanlock.log has on entries during that time frame.

mmm... that is very interesting...
both vm's are identical? are they server or desktops type? created
as thin copy or clone? what storage type are you using? did you
happen to have an open monitor on the vm that failed migration?
I wonder if it can be sanlock lock on the source template but I
can only see this bug happening if the vm's are linked to the template
can you look at the sanlock log and see if there are any warning
or errors?
All logs are in debug so I don't think we can get anything more
from it but I am adding Meital and Omer to this mail to help debug
this - perhaps they can think of something that can cause that
from the trace.
This case is really interesting... sorry, probably not what you
want to hear... thanks for helping with this :)

Failed live migration is wider spread than these two VM's, but
they are a good example because they were both built from the
same template and have no modifications after they were
created. They were also migrated one after the other, with one
successfully migrating and the other not.
Are there any increased logging levels that might help
determine what the issue is?

Hi Dafna,
No snapshots of either of those VM's have been taken, and
there are no updates for any of those packages on EL 6.5.
