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.

Robert

Subject: Re: [ovirt-users] NFS Storage Domain on OpenMediaVault

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
