Adding additional Storage domain NFS for ovirt 3.5

Question

I wanted to add an additional storage domain for my ovirt setup, but my problem is that everytime I try to add the Data / NFS I get this error:

2015-09-23 16:07:46,752 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.CreateStorageDomainVDSCommand] (ajp--127.0.0.1-8702-4) [34173edf] Failed in CreateStorageDomainVDS method

I have tried manually mounting the exported path and it works fine.

NFS exports have some extra requirements - they should be exported and accessible by all the hypervisors of course, but also, the export path should belong to 36:36

chown -R 36:36 /path/to/export

Folks usually forget the permissions. BTW, if you are using SELinux on the NFS machine, please make sure it is configured for NFS as well
