Package: linux-image-2.6.26-2-amd64
Version: 2.6.26-15lenny3
I am doing a stress test of my HA fileserver based upon
Lenny on 2 hosts. It uses drbd (protocol C), nfs-kernel-server
and heartbeat. The exported partition is formatted in XFS.
/etc/exports is
/data 172.22.96.0/23(rw,async,no_root_squash,no_subtree_check)
/var/lib/nfs is on a cluster file system shared between both hosts,
too. /etc/init.d/nfs-kernel-server had to be patched to make sure the
nfs daemons terminate (see http://bugs.debian.org/532276).
During the test I run on host1
while true; do \
/etc/init.d/heartbeat stop; \
sleep 120; \
/etc/init.d/heartbeat start; \
sleep 120; \
ssh host2 /etc/init.d/heartbeat stop; \
sleep 120; \
ssh host2 /etc/init.d/heartbeat start; \
sleep 120; \
done
The NFS partition was mounted on a Linux client (Opensuse). On
this host I ran
cd /mnt
for i in $(seq -w 0 99); do \
date; \
mkdir -p $i; \
pushd $i; \
tar xpf /var/tmp/linux-2.6.29.4.tar.bz2; \
popd; \
done
sync
date
Of course both loops were running in parallel. Host1 showed
after some time:

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.0 / Wheezy with a severity
less than important.
We don't have the ressources to reproduce the complete backlog of all older kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by sending
a mail to control@bugs.debian.org with the following three commands included in the
mail:
reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks
Cheers,
Moritz
