[CentOS] cluster suite & gfs problem since update

Just FYI, I figured out the problem.  I had set all of the clients up
with their IP address in the "target" field, but apparently the updated
rgmanager nfsclient.sh script now checks /var/lib/nfs/etab and sees
what's in there and does a compare, and etab always has the *hostname*
instead of the ip, so since it didn't match the script was marking it
bad.  Kinda stupid way of monitoring if you ask me, why they felt like
this was necessary I have no idea.  Just wanted to let anyone know that
may have set their clients up by ip address that the new update is going
to break them.
