[Users] NFS Advanced Parameters Greyed out on Existing Storage Domains

So I have read this BZ https://bugzilla.redhat.com/show_bug.cgi?id=855729 and these related ovirt BZs http://gerrit.ovirt.org/#/c/8110/ http://gerrit.ovirt.org/#/c/8797/ http://gerrit.ovirt.org/#/c/8798/ 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? -- Chris Noffsinger
