The fix is to change this on the serve side: # grep RPCMOUNTDOPTS /etc/default/nfs-kernel-server # --manage-gids is not compatible with oVirt. #RPCMOUNTDOPTS="--manage-gids" RPCMOUNTDOPTS="" > It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVXUH5B26FB... ... Although the actual export is ext4, not xfs. The issue is not related to the file system, and it is likely the same issue described in this thread. > 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? This seems to be incompatible NFS server defaults on Ubuntu. > Is my only option here to install an OS that supports SELinux? This is another option, RHEL (like) server is a safe bet. Nir
