Just triggered it again. My steps for it are:
- run all lockperf test
git://git.samba.org/jlayton/lockperf.git
via my test script:
#!/bin/sh
run_tests () {
echo $1
for i in `seq 10`;
do
rm -rf /tmp/a;
$1 /tmp/a > /dev/null
sync
done
for i in `seq 100`;
do
rm -rf /tmp/a;
$1 /tmp/a >> $2
sync
done
}
PATH=~/src/lockperf:$PATH
DIR=$1-`uname -r`
if [ ! -d "$DIR" ]; then
mkdir $DIR
fi
CPUSET=`cat /sys/devices/system/node/node0/cpulist`
taskset -pc $CPUSET $$
sudo sh -c 'for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor ; do
echo performance > $i ; done'
for c in `seq 8 32 128`; do
for l in `seq 100 100 500`; do
time run_tests "posix01 -n $c -l $l " $DIR/posix01-$c-$l.data
time run_tests "posix02 -n $c -l $l " $DIR/posix02-$c-$l.data
time run_tests "posix03 -n $c -l $l " $DIR/posix03-$c-$l.data
time run_tests "posix04 -n $c -l $l " $DIR/posix04-$c-$l.data
time run_tests "flock01 -n $c -l $l " $DIR/flock01-$c-$l.data
time run_tests "flock02 -n $c -l $l " $DIR/flock02-$c-$l.data
time run_tests "lease01 -n $c -l $l " $DIR/lease01-$c-$l.data
time run_tests "lease02 -n $c -l $l " $DIR/lease02-$c-$l.data
done
done
sudo sh -c 'for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor ; do
echo powersave > $i ; done'
And after that rebuild a new kernel. That was all.
This time I saved the logs. xfs_repair was not so happy either.
cheers,
daniel
