Overview
Runs hdparm -t, seeker and Nates dd script.
By default each test is run 3 times to get a good running average.
Outputs are cleaned up to provide usable information
For Nates dd test you will need to have the drive mounted and listed in fstab
Script
#!/bin/bash
testpath=`grep $1 /etc/fstab | awk '{print $2}'`
testcount=3
echo "Testing hdparm -t $1"
for i in `seq 1 $testcount`;
do
hdparm -t $1 | grep "Timing"
done
if [ `which seeker 2>/dev/null` ]
then
echo "Testing seeker $1"
for i in `seq 1 $testcount`;
do
seeker $1 | grep "Results"
done
else
echo "Seeker is not installed, please install from rpmforge: 'yum install seeker'"
fi
if [ `which pv 2>/dev/null` ]
then
echo "Testing DD pv"
echo "Write Test"
for i in `seq 1 $testcount`;
do
sync
dd if=/dev/zero bs=1M count=2048 2>/dev/null | dd of=$testpath/ddfile 2>&1 | grep copied
done
echo "Read Test"
for i in `seq 1 $testcount`;
do
sync
cat $testpath/ddfile | pv -trb -s 2G > /dev/null
done
rm -f $testpath/ddfile
