Hi David,
Caught your note about bonnie, actually do some testing myself over the weekend.
All on older hardware for fun - dual opteron 285 with 16GB RAM. Disk systems
is off a pair of SuperMicro SATA cards, with a combination of WD enterprise and
Seagate ES 1TB drives. No ZIL, no L2ARC, no tuning at all from base FreeNAS
install.
10 drives total, I'm going to be running tests as below, mostly curious about
IOPS and to sort out a little debate with a co-worker.
- all 10 in one raidz2 (running now)
- 5 by 2-way mirrors
- 2 by 5-disk raidz1
Script is as below - if folks would find the data I collect be useful
information at all, let me know and I will post it publicly somewhere.
freenas# cat test.sh
#!/bin/sh
# Basic test for file I/O. We run lots and lots of the tradditional
# 'bonnie' tool at 50GB file size, starting one every minute. Resulting
# data should give us a good work mixture in the middle given all the different
# tests that bonnnie runs, 100 instances running at the same time, and at
different
# stages of their processing.
MAX=100
COUNT=0
FILESYSTEM=testrz2
LOG=${FILESYSTEM}.log
date > ${LOG}
echo "Test with file system named ${FILESYSTEM} and Configuration of..." >>
${LOG}
zpool status >> ${LOG}
# DEMAN grab zfs and regular dev iostats every 10 minutes during test
zpool iostat -v 600 >> ${LOG} &
iostat -w 600 ada0 ada1 ada2 ada3 ada4 ada5 ada6 ada7 ada8 ada9 > ${LOG}.iostat
&
while [ $COUNT -le $MAX ]; do
echo kicking off bonnie
bonnie -d /mnt/${FILESYSTEM} -s 50000 &
sleep 60;
COUNT=$((count+1));
done;
