my NSD servers as gateways to get additional throughput (with both native
gpfs protocol and NFS protocol), which worked well; we definitely got the
increased traffic. However, I wouldn’t do it again through choice. As
Venkat says, if there is a problem with the remote cluster, that can affect
any of the gateway nodes (if using gpfs protocol), but also, we had a problem
with one of the gateway nodes, where it kept crashing (which is now resolved)
and then all filesets for which that node was the gateway had to failover
to other gateway servers and this really messes everything up while the
failover is taking place. I am also, stupidly, serving NFS and samba from
the NSD servers (via ctdb) which I also, would not do again !</font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri">It would be nice if there was a way to
