Gents, I'm sending this email for archiving purposes: It's been a while since my last update on this topic. It turned out that although only one node, randomly, at a time lost connection to storage, the issue was not at all with ovirt, but with the storage.
I'd like to refer to these 2 topics for more information: http://lists.freebsd.org/pipermail/freebsd-net/2014-March/038061.html and http://lists.freebsd.org/pipermail/freebsd-net/2014-February/037967.html.
