Hi.
My setup is 3 servers
1. Frontend (engine).
2 Ovirt node
3. Nfs server (debian)
From the Frontend (engine) :-
-bash-4.2$ ls -la
/tmp/test/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/d1fcc1ae-dcf5-426e-a99f-3a48e84c5ae3/
total 2097168
drwxr-xr-x. 2 vdsm kvm 4096 Mar 28 2012 .
drwxr-xr-x. 3 vdsm kvm 4096 Mar 28 2012 ..
-rw-rw----. 1 vdsm kvm 2147483648 Mar 28 2012
9fe193c9-7139-4a6c-933a-c6f31d5e96bd
-rw-r--r--. 1 vdsm kvm 317 Mar 28 2012
9fe193c9-7139-4a6c-933a-c6f31d5e96bd.meta
I have (now) write access with vdsm user from here
From the node (look at ownership....) :-
-bash-4.2$ ls -la
/rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/d1fcc1ae-dcf5-426e-a99f-3a48e84c5ae3/
total 2097168
drwxr-xr-x. 2 4294967294 4294967294 4096 Mar 28 13:21 .
drwxr-xr-x. 3 4294967294 4294967294 4096 Mar 28 13:05 ..
-rw-rw----. 1 4294967294 4294967294 2147483648 Mar 28 13:05

-rw-r--r--. 1 4294967294 4294967294 317 Mar 28 13:05
9fe193c9-7139-4a6c-933a-c6f31d5e96bd.meta
Also
From the engine - mount command:-
10.0.0.190:/storage1/ on /tmp/test type nfs
(rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.0.190,mountvers=3,mountport=35065,mountproto=udp,local_lock=none,addr=10.0.0.190)
- note that the NFS share wasn't mounted until I mounted it...
From the node - mount command
10.0.0.190:/storage1/ on /rhev/data-center/mnt/10.0.0.190:_storage1
type nfs4
(rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=10.0.0.101,minorversion=0,local_lock=none,addr=10.0.0.190)
- looks like nfs4 on the node........
Any ideas anyone ?
Cheers

The fies it refers to do not exist on Debian - i.e
/etc/sysconfig/nfs and/etc/nfsmount.conf - they do not exist...
Do you know the equivalent on Debian ?
Sorry, i use fedora, and I dont know the equivalent of Debain.
Maybe asking the big brain(google) might help. There should be an
equivalent way of doing the same on debian.
Also in my case v4 was not a issue, as much as the perms and uid:gid
were, so look further to see perms and selinux booleans are
set correctly in your setup.
