Hello,
Is it possible to use Ubuntu to share an NFS export with oVirt?

I'm trying to setup a Backup Domain for my environment.

I got to the point of actually adding the new Storage Domain.

When I click OK, I see the storage domain appear momentarily before disappearing, at which point I get a message about oVirt not being able to obtain a lock.

It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVXUH5B26FBFCGYLG62JUSB5SOU2MN7/#IZTU744GVKY5OJT4QOULLZVKGYADXDOO ... Although the actual export is ext4, not xfs.

From what I'm reading on that thread and elsewhere, it sounds like this problem is a result of SELinux not being present, is that correct?

Is my only option here to install an OS that supports SELinux?
