[ovirt-users] Sanlock issues after upgrading to 3.4

[Jairo Rizzo]

Hello,

I have a small 2-node cluster setup running Glusterfs in replication mode :

CentOS v6.5
kernel-2.6.32-431.17.1.el6.x86_64
vdsm-4.14.6-0.el6.x86_64
ovirt-engine-3.4.0-1.el6.noarch  (on 1 node)

Basically I was running ovirt-engine v 3.3 for months fine and then
upgraded to latest version of 3.3.X two days ago and could not join the
nodes to the cluster due to a version mismatch,basically this:
https://www.mail-archive.com/users@ovirt.org/msg17241.html  . After trying
to correct this problem I ended up upgrading to 3.4 which created a new and
challenng problem for me. Every couple of hours I get error messages like
this:

This makes one of the nodes not be able to see the storage and all its VMs
will go into pause mode/stop. Wondering if you could provide some advice.
Thank you
