NFS Emergency - RPC and NFSD online but no connection??

[Kaya Saman]

Hi guys,

this is a really interesting yet annoying issue I'm having.....

I had a fully working NFS setup until earlier today when I had a failed 
attempt at recovering an external hard disk that I fitted into my system 
internally.

Now this disk has nothing to do with the system and is used with Linux 
hence it runs the ext3 filesystem but since the BSD machine is the only 
desktop I have I thought it a good idea to recover from there.

Anyhow, I removed the drive and in the mean time compiled Transmission 
bit torrent client from ports and a failed attempt to compile Amule2 
with a dependency failing to compile; if memory serves me well I think 
it was cryptopp or something with pp at the end anyway. Sorry for lack 
of stating on here if it necessary I will find this out and post it 
immediately.

Well.... just to say now that I can't mount what I used to be able to 
mount before.

I built a little shell script so that I didn't need to use fstab from my 
Linux box and all I get as response is this:

:~# ./BSD2.sh
mount.nfs: mount system call failed

Syntax in shell script is:

mount -t nfs -o rw 172.16.0.200:/mnt/SATA /mnt/BSD2

I have checked the logs on the server /var/log/messages only there isn't 
any information at all being given??

 From BSD if I try to restart or stop nfsd or mountd I get this:

rd1# /etc/rc.d/nfsd stop
Stopping nfsd.
^C

rd1# /etc/rc.d/mountd restart

which has held there for  a while now meaning that it's probably crashed 
or something?

Netstat claims everything is online:

rd1# netstat -ap udp

and I don't have any firewall in place at all!!

Output of uname -a:

rd1# uname -a
FreeBSD rd1.optiplex-networks.com 8.0-RELEASE FreeBSD 8.0-RELEASE #0: 
Sat Nov 21 15:48:17 UTC 2009     
root at almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

The system is a 32bit PIV running at 2.4GHz with 480MB of RAM.

Really I'm not sure what to do if I need to upgrade NFS as one of it's 
dependencies has been upgraded or something else as it's just not working??

Actually I've just typed in exit after su - 'ing to root from an SSH 
session and the session looks like it's hung on me...??

Also I've had the system running into kernel panic and restarting a lot 
earlier as the load average went up is what logwatch seems to show.

Can anyone help me out of this dilemma??
