So I have read this BZ https://bugzilla.redhat.com/show_bug.cgi?id=855729

So forgive me but I am a little confused. I have some existing NFS
Storage domains that I was not paying attention and attached without doing
any advanced parameters in RHEV 3.1

Now the NFS Advanced Parameters box is greyed out.

So now that I have attached these domains I cannot change the advanced nfs
option such as change it to Nfs4 from 3 or rsize and wsize?

Maybe if I was using upstream oVirt instead of Rhev 3.1 I would be able to
make the changes in vdsm.conf and they would be honored?

It's the same in oVirt 3.1 and RHEV 3.1, see this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=835543

As long as VDSM is current, you should be able to change the the nfs_mount_options in vdsm.conf to get what you want. You would need to use this route instead of/in addition to the advanced options anyway, because they only allow modification of nfs version, retrans, and timeout and not rsize/wsize.

(2 other options are a) modify the db directly (storage_server_connections table) for the available advanced options (not rsize/wsize), or b) attach the sd as posix and specify the mount options, but IMO the vdsm.conf method above is easier and cleaner.)

Hope that helps,
Greg
