Questions about HUP'ing nfsd

[Michael Smith]

Hello All:

We have a NAS that's running 6.2 with nfds, mountd, rpc_statd,  
rpcbind and rpc_lockd.  Last night we had a scenario where nfs  
clients, once disconnected, couldn't reconnect to the NAS, reporting  
RPC timeouts.

We attempted to restart all of the services above in various orders,  
but we were not able to get the clients reconnected.  We ultimately  
rebooted the NAS server and all was well.

My question is, in troubleshooting this sort of thing, is there a  
proper sequence for stopping and restarting the various services  
associated with nfs?   Any hints would be greatly appreciated.

Regards,

Mike
