NFS problem

[Dominick Samperi]

Does anyone know how to unmount a file system that is being exported from
a dead server? Under SunOS I get the message "file system busy" when
I try to unmount it, and all new processes hang for a minute or two
due to the dead server. Furthermore, intr does not break out of the
hung processes, even though the file system is mounted soft and
with intr turned on.

It seems to me that NFS works well when all servers are up, but has real
problems when one or more servers go down.
