[ovirt-users] Cannot find master domain

Thu Jul 28 10:54:17 EDT 2016

Error from vdsm log: Permission settings on the specified path do not allow access to the storage. Verify permission settings on the specified storage path.: 'path = /rhev/data-center/mnt/glusterSD/172.16.0.11:_ovirt'

I remember another thread about a similar issue - can you check the ACL settings on the storage path?
