Thanks for the response.

As it turned out, the issue was on the export where I had to remove subtree_check and added no_root_squash and it started working.

Being new to the setup, I am still trying to work through some config issues and deciding if I want to continue. The main thing I am looking for is good HA and failover capability. Been using Proxmox VE and I like the admin of it, but failover still needs work. Simple things like auto migration when rebooting a host does not exist and is something I need.
for RHEV, you can check the Cluster scheduling policies

Does sanlock user has rights on the ...../dom_md/ids ?

Check the sanlock.service for issues.
journalctl -u sanlock.service

I have a clean install with openmediavault as backend NFS and cannot get it to work. Keep getting permission errors even though I created a vdsm user and kvm group; and they are the owners of the directory on OMV with full permissions.

The directory gets created on the NFS side for the host, but then get the permission error and is removed form the host but the directory structure is left on the NFS server.

Logs:

From the engine:

Error while executing action New NFS Storage Domain: Unexpected exception
