Should work without problems.

My test-clusters are using this setup and i faced no problems even under
bonnie++ load...

I use ggaoed because other target-creators didn't allowed (i last
checked this over a year ago) access to the same target over lo and eth

I can give more details (eg. configs) if you need them.

GFS as blockdevice filesystem and NFS as network protocol can't be
compared easily...

An NFS-share is hosted on some random (even GFS is possible) blockdevice
filesystem hidden behind the protocol of the NFS-server. So this
NFS-servers architecture plays a huge role in such a comparison of
