  I'm having the same problem - the service won't shutdown cleanly as it 
can't unmount the file systems - which it can't unmount due to some one 
logging in with SSH and their home directory is on that volume.

  I've also had an issue with the cluster manager not shutting down 
nfsd, so a volume won't unmount 'cause an NFS client is still attached. 
I think I might have nailed that one, but there is little I can do about 
people with interactive logins.
(It's acceptable to terminate their logins with extreme prejudice, but 
not to disable the SSH service, as I need that to admin the machine :-)
