bash shell script for ioping disk I/O tests
Hi guys
I'm writing a bash shell wrapper script for ioping but am stuck.
Here's the snippet of the non-working code
Code:
SOFTRAIDCHECK=`cat /proc/mdstat | grep active`
if [[ ! -z $SOFTRAIDCHECK ]]; then
DEVICES='{sd*,md*}'
else
DEVICES='sd*'
fi
echo "**********************************************"
echo "seek rate test (default 1MB working set size)"
echo "**********************************************"
for DEV in /sys/block/${DEVICES}
do
DEV=`echo ${DEV} | sed -e 's/\/sys\/block\///g'`
echo "seek rate: /dev/${DEV}"
ioping -R /dev/${DEV} | grep -E '(iops|mdev)'
echo ""
done
when run i get this error
Code:
**********************************************
seek rate test (default 1MB working set size)
**********************************************
seek rate: /dev/{sd*,md*}
ioping: stat "/dev/{sd*,md*}" failed: No such file or directory
but if I change
Code:
for DEV in /sys/block/${DEVICES}
to
Code:
for DEV in /sys/block/{sd*,md*}
it works and outputs
Code:
**********************************************
seek rate test (default 1MB working set size)
**********************************************
seek rate: /dev/sda
617 requests completed in 3006.7 ms, 310 iops, 1.2 mb/s
min/avg/max/mdev = 0.1/3.2/46.6/5.6 ms
seek rate: /dev/sdb
2121 requests completed in 3001.1 ms, 4564 iops, 17.8 mb/s
min/avg/max/mdev = 0.0/0.2/0.9/0.1 ms
seek rate: /dev/sdc
1762 requests completed in 3001.8 ms, 3324 iops, 13.0 mb/s
min/avg/max/mdev = 0.1/0.3/2.4/0.3 ms
seek rate: /dev/md0
1517 requests completed in 3001.0 ms, 2985 iops, 11.7 mb/s
min/avg/max/mdev = 0.1/0.3/1.0/0.2 ms
Any tips or suggestions are much appreciated 
George

ok think i figured a workaround
change from
Code:
if [[ ! -z $SOFTRAIDCHECK ]]; then
DEVICES='{sd*,md*}'
else
DEVICES='sd*'
fi
to
Code:
if [[ ! -z $SOFTRAIDCHECK ]]; then
DEVICES=`ls /sys/block/ | grep -E '(^sd|^md)'`
else
DEVICES='sd*'
fi
