Can you check the firewall on each of those machines ( iptables -L )
and paste that here. Also, is this network dedicated to Lustre? Lustre
can easily saturate a network interface under load to the point it
becomes difficult to login to a node if it only has one interface. I'd
recommend using a different interface if you can.

On the oss can you ping the mds/mgs using this command--
lctl ping [EMAIL PROTECTED]
If it doesn't ping, list the nids on each node by running
lctl list_nids
and tell me what comes back.
