[Partial SUMMARY] Automount grief

had a couple of quick replies, thanks to
        Joe Fletcher
        Jim Lola
There replies are below.

After stopping and starting the network a few times, I have managed to free
the one important mount point - so the pressure is off.

I still have another directory locked though, and automount now will not
start. Both get the error NFS2: server `this machine name` not responding
still trying. Interestingly, fuser on the directory name also gets the
error.

I have looked through the output of
        lsof
        ps -ef
for any suspicious looking programs, but - again - to no avail.

Versions of the software
        Machine with locked directory - 5.0
        Machine contain export dir - 4.0g

Any further ideas? At the moment, it's looking like a scheduled reboot on
the weekend.

Cheers

Paul

p.s. The original problem came from enabling a second network card for
backups, then bouncing the network.

======================================================================

Sound like your are already in trouble. When you say you bounced the NICs -
how and why? Have you tried rcinet restart? It's a bit drastic but it
might help.

If something has a lock on the nfs directory use fuser to find the
offending process and kill it. I'd start with this rather than the rcinet
restart.

======================================================================
Check the server that is serving out the file systems and verify that the
file
systems are available and in the /etc/exports.

On the client system, we use /etc/auto.direct and /etc/auto.master for
automount
or autofs (in 5.1). If all this checks out, the only thing we've found to
clear
this condition is to reboot the client system.

Its for this very reason that when 5.1 came around, we abandoned automount
and
went with autofs. autofs is like a parallelized amd and we have not
encountered
any problems with it. When we used automount, we had weekly issues with
this
program.

hello

Need some quick help....

I bounced my network cards this morning to define the second card, and the
automounts between machines have died. I have rebooted one machine (the only
one possible) and that fixed that machine, but my production machine is
still in a bad way - I would prefer not to bounce it...

I cannot do an 'ls' on the directory that was automounted, it comes back
with

NFS2 server `this machine name` not responding still trying

I have run
/sbin/rc3.d/S19nfs stop
/sbin/rc3.d/S19nfs start
/sibn/rc3.d/S20nfsmount stop
/sibn/rc3.d/S20nfsmount start

but to no avail...

I have searched the archives, this question has been asked before, but there
is no summary that works...

One of the automounted directories is now in a bad state. I cannot do an ls
on the directory name, and cannot unmount the directory - so it seems that
something is holding it open.
