It is a problem area which we have faced a lot which causes the services and server to hang up whenever a server which is mounted on another Liux server goes down.

I tried this trick and can get some of the commands unlocked. However unmounting I get "Stale file handle". The unmount -f and -l combinations give the same "stale file handle"

Any ideas?
