I'm in the early stages of testing an ovirt install, using the official ovirt engine
packages + F16.
I configured a storage domain to connect to our gluster storage via NFS (pity we
can't use gluster natively yet). On the engine server, I added Nfsvers=3 to
/etc/nfsmount.conf as instructed here:
I then installed a host via ovirt-node (2.3.0-1) and successfully added the host, but it
refuses to connect to our storage domain because it's attempting to mount via NFS4.
When I add Nfsvers=3 to /etc/nfsmount.conf on the host, it comes to life. Of course, that
will be reset after a reboot.
So what are my options here, other than not use ovirt-node? AFAIK, gluster doesn't
export NFS4, let alone have options to disable it. And I don't see any way to add nfs
mount options when defining a storage domain...
Take a look at the /etc/vdsm/vdsm.conf configuration file in the host.
There is a nfs_mount_options parameter there that you can use.
You can also make the /etc/nfsmount.conf file persistent with "persist
/etc/nfsmount.conf" (I haven't tested this myself).
