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 may be he issue describe here:
https://github.com/oVirt/ovirt-site/pull/2433
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.
