I'm attempting to mount a share from a TrueNAS server in oVirt through the Storage
> Storage Domains UI as a New Domain. Whenever I try to add the domain (as
server:share), it kicks back a Permission Denied error. Looking at the vdsm.log file, I
see the below snippet:

Stepping it through, am I correct that I'm seeing vdsm not able to create the local
directory for the NFS mount? It previously was able to mount an NFS share from the host to
itself when I initially setup the server for testing.
When I do an ls -l on the directory it's trying to create the mount point in, I see
ownership looks correct.
[root@ovirt ~]# cd /rhev/data-center/
[root@ovirt data-center]# ls
c7d57de0-6ba8-11ee-9a48-00163e1989b9 mnt
[root@ovirt data-center]# ls -l

total 0
drwxr-xr-x. 3 vdsm kvm 50 Nov 17 10:14 ovirt.theclocktower.home:_home_ovirt__storage
[root@ovirt mnt]#
Is there something missing? Something that got misconfigured, maybe? Or something I can
configure to fix this?
7:32 p.m.
Also, I can mount that NFS share just fine from cli or Cockpit's Storage interface to
the /mnt directory. I'm logged into Cockpit and have SSH'd into the ovirt host as
root, though, so that may play into why I can mount those without issue. Still, the oVirt
management interface should be using the vdsm service, right? And that service should have
rights to the /rhev/data-center/ directory?
1:46 a.m.
I have the same setup running here and the only hiccup experienced was
the permission set on TrueNAS.
You'll need to modify your filesystem permissions to allow read/write
for user/group IDs 36:36. I created local user 'ovirt' and corresponding
group with IDs '36' on TrueNAS and granted only that user permission to
access that share.
I suspect that'll do the trick.

Okay, I don't see the person's reply to this thread (maybe it was a direct reply
to me?), but now I can authenticate. Except... now it's complaining it can't get
sanlock...

Why is so much of this needing my personal touch to setup? Shouldn't access through
36:36 be sufficient? Sorry, just not happy that something that I thought would be a
straightforward process is becoming more involved than I thought.
2:48 a.m.
Finally, it let me create the storage domain. Went in and cleared out all of the previous
attempts (that apparently it didn't know to clear out on its own). After that, it
created successfully.
