3:26 p.m.
Any advice or other things to check? I'm at a loss as to what's causing this and I
can't add more nodes to the same cluster without a working NFS as I understand it.

I believe it's using protocol version 3, and the nfs-kernel-server package is 1.2.8-9.
The Netgear is basically Debian Linux with their proprietary packages thrown in for
management. The kernel version on the Netgear is 4.4.91.x86_64.1
You think SELinux on the NAS or the oVirt box? I don't have the oVirt box in enforcing
mode, it's in Permissive mode due to an earlier SELinux issue I ran into on it. I
don't remember the details on why at the moment, but it was when I originally setup
the box in February.

What version of NFS do you have on the Netgear?
It could be a SELinux configuration.

Currently running version 4.1.6.2-1.el7.centos
The logfile is attached and the relevant entries are at the bottom of the log. It
evidently doesn't get rotated, so it contains entries going back to when I first setup
the box in 2/17.
I've perused that page countless times now, but I still can't get it to work on
this setup. In the sanlock log file, the attempts to add the domain end in "s2
add_lockspace fail result -19" I don't know much about sanlock, but I wish I knew
what result -19 meant, perhaps it would clue me in. Thanks for your help.

Hi,
Which version are you using ?
Can you provide /var/log/sanlock.log ?
Also check this page:

Hello all,
I've got an oVirt setup that I'm trying to add an NFS storage domain from a
Netgear ReadyNAS 3220 NAS server. I've setup the NFS exports as follows:
"/data/Virtual_Machines"
127.0.0.1(insecure,insecure_locks,no_subtree_check,crossmnt,anonuid=36,anongid=36,all_squash,ro,sync)
10.50.31.83(insecure,insecure_locks,no_subtree_check,rw,root_squash,anonuid=36,anongid=36,crossmnt,sync)
Where 10.50.31.83 is my oVirt box. I've made sure that /data/Virtual_Machines is
chowned to 36:36 and each time I add it, it fails after performing the following steps:
The oVirt box mounts the file share, creates all the files and directories, they are owned
by 36:36 correctly, the new storage domain box closes and I am returned to the oVirt
Management console where within a couple of seconds, I'm presented with a dialog box
that says:
Operation Canceled
Error while executing action Attach Storage Domain: AcquireHostIDFailure
I've looked through logs and found the there is a SanlockException(19, "Sanlock
lockspace add failure', 'No such device')) that seems to be the culprit.
Just to test, I've used the same exports file on my local machine (which has limited
storage), and shared out a directory via NFS. I can successfully connect and use that
storage within oVirt, but of course it does me no good. The RN3220 has approximately 10TB
free on it at the moment, so it's not a space issue and as mentioned the directories
and files all get created and are owned by vdsm:kvm It really feels like something's
up with the ReadyNAS, but I'm not sure what? I've attached the vdsm.log file and
have access to any other logs you may need.
Any help would be greatly appreciated as I'm about to bring up another node and really
need access to network storage. I'm currently using only local storage attached to the
host.
