[ovirt-users] nfs storage permission problem

[Bill James]

just to close off this issue.
I found problem.
My /etc/exports file had a space in it where it shouldn't have (between 
* and options).
This seemed to acceptable with older versions of centos7.2 but on my 
newer host with latest centos7.2 (3.10.0-327.13.1.el7.x86_64) it only 
mounted read-only. maybe default changed from rw to ro?

I fixed exports file and now both versions of centos work.

/mount_point *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
