Avoiding NFS clients Hang when NFS server dies

Hi All,

My tru64 boxes (mostly v4.0G) are heavy crossmounters
of disks served on other tru64 hosts and Linux.

Problem is that if any one host goes down, all other
hosts hang with a df. Additionally, other programs
that utilize "df" (eg. our backups, ssh --when it
tries to generate random seed runs a number of
commands, including df) hang as well.

I have read and implemented two "thought" solutions:

1. mounting inside a dir i.e.
mount -t nfs HOSTA:/dirAAA /HOSTA/dirAAA
instead of:
mount -t nfs HOSTA:/dirAAA /dirAAA
It is not suggested to mount nfs dirs under root.

2.Using the "soft" option for mounting (default=hard).

None of these are a cure. Any additional suggestions
out there?

_Thanks

Richard
