I have set up a Linux-HA cluster (2 hosts) using kernel 2.6.30.5, drbd 8.3.2
and Heartbeat. The data partition is formatted in reiserfs. It is exported via
NFSv3 to 3 other Linux hosts.
For a stress test I run a loop to shutdown heartbeat on the current primary,
wait 5 minutes for the other host to take over and to make sure the NFS
timeouts on the clients have expired, startup the local heartbeat again, and
wait
another 30 seconds. A complete cycle takes 11 minutes.
To put some load on the cluster I have started 3 kernel builds in parallel on
each of the 3 NFS clients.
After some time I got the attached crash. It seems that it happened when
heartbeat tried to unmount the data partition. I had to reboot, check the file
system (it was dirty), and start heartbeat again. After a few cycles I got the
same problem again, but this time on the other host. After that I stopped
testing.
