[ovirt-users] ovirt - can't attach master domain

[paf1 at email.cz]

Hi,
due cleaning envir. I restarted all nodes and ovirt mgm server too,
Now I can't  get master domain ON. Tried to move to diff. storage with 
same result.
All storages are OFF and DataCenter OFF too.
All NFS mount points are connected and writeable via ovirt mountpoint.
Any idea how to fix thi - quicky

Rhel 7.1 /  KVM 2.1.2 / libvirt 1.2.8-16 / vdsm 4.16.27 / gluster 
3.7.5.1 / ovirt 3.5.2
