Subject: NFS hang in 2.6.21.1
Date: Mon, 21 May 2007 07:18:04 -0700 (PDT) [thread overview]
Message-ID: <767985.78880.qm@web54407.mail.yahoo.com> (raw)
Team,
I have been attempting to put together a linux HA NFS
server for my home environment. I am currently
running two Debian etch 4.0 machines both running
vanilla 2.6.21.1 kernels that I compiled (exception
being the nvidia driver for video). When I attempt to
do some performance benchmarks, a test of bonnie++
makes the NFS client stuck in a non-responsive
non-killable state. The NFS server at this point is
not busy doing anything so I believe there may be some
condition leading to a deadlock in the client.
jfrisk@evil:~$ df -k .

jfrisk@evil:~$ /usr/sbin/bonnie++ -f -s 100 -n 1 -r 0

Rewriting...
This is where the bonnie program hangs.
frisk@evil:~$ ps aux | grep bonnie
jfrisk 6882 0.7 0.0 2708 1012 pts/3 D+
09:11 0:00 /usr/sbin/bonnie++ -f -s 100 -n 1 -r 0
Top shows the user load at 1.00 (before starting is
0.10) but nothing else of importance is running on
the system.
I can reproduce this bug pretty consistently. I have
these machines for use by anyone on the team so I
would appreciate being guided on what to do next to
help debug this issue. Thanks in advance!
