Hi Dan,

Sorry for the late reply. All I can see is this:

I've tried to use version 3 in the server to avoid version problem (as
centos uses nfsv4 as default, BTW why you restrict to version 3?) but it
didn't work, it seems to continue to use v4
Manually:

[root at ovirt3 vdsm]# mount -t nfs
ovirt2.montecarlotv.com.uy:/home/exports/export /mnt/
[root at ovirt3 vdsm]# mount
/dev/mapper/vg_ovirt3-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/vg_ovirt3-LogVol03 on /glusterfs type btrfs (rw)
/dev/mapper/vg_ovirt3-lv_home on /home type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
ovirt4.montecarlotv.com.uy:/gluster on
/rhev/data-center/mnt/glusterSD/ovirt4.montecarlotv.com.uy:_gluster type
fuse.glusterfs (rw,default_permissions,allow_other,max_read=131072)
ovirt2.montecarlotv.com.uy:/home/exports/export on /mnt type nfs
(rw,vers=4,addr=192.168.128.81,clientaddr=192.168.128.82)

but with ver 3:

mount -t nfs -o nfsvers=3
ovirt2.montecarlotv.com.uy:/home/exports/export /mnt/

just never connects.
Regards,
