Hey Amit,
Thanks for the response. Here's what I've got:

Here's the perms on the folder (/mnt/ovirt on NFS server):

Root of share:

I think selinux is not supported on your file system. Here is a working setup:
On the host:
# ls -lhZ /rhev/data-center/mnt/nfs1\:_export_1/
total 0
drwxr-xr-x. 5 vdsm kvm system_u:object_r:nfs_t:s0 48 Jun 20 03:56
56ecc03c-4bb5-4792-8971-3c51ea924d2e
On the server:
# ls -lhZ /export/1
total 0
drwxr-xr-x. 5 vdsm kvm system_u:object_r:unlabeled_t:s0 48 Jun 20
03:56 56ecc03c-4bb5-4792-8971-3c51ea924d2e
Inside of that:
drwxrwxr-x 2 vdsm kvmovirt ? 8 Aug 4 18:52 dom_md
drwxrwxr-x 2 vdsm kvmovirt ? 2 Aug 4 18:52 images

Here's what I see:
...
2020-08-04 13:52:58,819-0500 ERROR (jsonrpc/1) [storage.initSANLock]

sanlock.SanlockException: (19, 'Sanlock lockspace write failure', 'No such

I think this is this bug:
https://bugzilla.redhat.com/1778485
Sanlok gets EACCESS - probably because selinux is disabled on the server,
or not supported with ZFS, and then it returns ENODEV.
Unfortunately this was not fixed yet in sanlock.
To fix this, try to get selinux working on your server, or use another
filesystem
instead of ZFS. ZFS is not tested with oVirt, so while it may have
great features,
you may have even more trouble later even if you can get it working.
