NFS & rebooting

[Troy Settle]

All,

A long time ago (3.x days?), whenver I rebooted an NFS server, all the 
client machines with mounted filesystems would completely freak out.  
I'm not talking about application errors, but that the nfs mounts were 
totally unresponsive.  I couldn't unmount the filesystems and I couldn't 
remount them, the only thing I could do, was to force a reboot on the 
client boxes, after which, they would come up and mount their 
filesystems without issue.

I'm looking again, at using NFS for my mail server setup, but need to 
know what the ramifications are if I need to reboot the NFS server, or 
if it's forced to reboot without the clients first dismounting any 
filesystems.

Thanks,
