lol that first paragraph didnt make any sence... was supposed to read
"I decided to try and re-mount the ISO domain using mount -o vers=3 ovirtmgr.foo.com:/mnt/ISO /rhev/data-centre/mnt/ovirtmgr.foo.com:_mnt/ISO and the mount was correctly mounted with vdsm.kvm permissions and then immediately the ISO appeared in the webUI..."

Subject: SOLVED: Re: [Users] Unable to add ISOs to default ISO storage domain
Turns out the problem is something to do with using NFSv4....
looking off the back of this thread https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/662711
I decided to try and re-mount the ISO domain user /rhev/data-centre/mnt/ovirtmgr.foo.com:_mnt/ISO
and immediately the ISO appeared in the webUI...
So, looks like the ovirtmgr host, needs to only use nfsv3, so the client does not try and negotiate v4 first...
i was able to force "no v4" on the ovirtmgr host, by adding
RPCNFSDARGS="-N 4"
to /etc/sysconfig/nfs, then restarting NFS server, systemctl restart nfs-server.service
Then i remounted the ISO domain on the hypervisor, and it just worked.
So the problem is, NFSv4 server with NFSv4 client = issues.... which make sence, as all the other hosts i used to mount the export, was an nfs3 client only...
Thanks for everyone for their assistance.. hopefully someone might be able to reproduce this, and or resolve it the same way.
Cheers,

Subject: Re: [Users] Unable to add ISOs to default ISO storage domain
ok - here we go.. shed some light on the situation...
it looks like the ISO mount is being mounted as user/group nobody on the hypervisor....
drwxr-xr-x. 3 nobody nobody 4096 Feb 10 02:52 ovirtmgr.foo.com:_mnt_ISO
This might explain it because the vdsm user cannot read the iso as its mode 640 nobody.nobody...
However on the iso domain host - the permissions are correct.. so the hypervisor isnt mounting the path correctly
Its just on the hypervisor node that its mounting as nobody.nobody... i can mount the iso share to any other linux or mac host, and it mounts with id/guid 36.36 as normal...
I initially thought that the user nobody and group nobody were somehow mapped to id 36, but this isnt the case (its normal, 99)...

$ mount ovirtmgr.rsp.com.au:/mnt/ISO test/
$ su - vdsm
This account is currently not available.
In /etc/passwd, the account does not have a valid shell... should it have?

Spyro,
I am also running out of ideas, but I want to verify a few more things
before I can safely say that there isn't a problem with the NFS ISO domain.
On the hyper-visor, can you..
1. mount ovirtmgr.foo.com:/mnt/iso /mnt/isodir
2. su - vdsm
3. cd
/mnt/isodir/23340f35-95ca-4b46-90ec-0c8b83a82786/11111111-1111-1111-1111-111111111111
4. ls
Does that work?
Cheers,
Keith
