Prerequisites

XFS & lsscsi need installing: 

yum install xfsprogs.x86_64 lsscsi

As does IOZONE: 

yum install iozone

Preparing the data filesystems

All available block devices in the attached disk enclosure will be used for this test. None of the drives in the front-end server will be used.

Get the list of available block devices

Use lsscsi to identify the drives to be tested (in this case, /dev/sdc to /dev/sdr): 

[root@nodea ~]# lsscsi

Create an XFS filesystem on each drive

The basic command for this is: 

mkfs.xfs -l version=2 -i size=1024 -n size=16384 -d su=64k,sw=1 <block device>

So can be scripted as follows: 

for i in {c..r};
do
	mkfs.xfs -l version=2 -i size=1024 -n size=16384 -d su=64k,sw=1 /dev/sd${i} &
done

Create mount points

Create mount points in /srv/castor/XY where XY ranges from 1 to the number of available block devices. For example, it will be 16 on a 16-bay disk enclosure.
This can be scripted as follows: 

mkdir /srv/castor
for i in {1..16};
do
	mkdir /srv/castor/${i}
done

Mount filesystems to mount points

Mount these filesystems using the following options: logbufs=8,logbsize=256k,noatime,swallow,inode64
This can be scripted to add mount point to /etc/fstab as follows: 

n=1

for i in {c..r}
do
	echo "/dev/sd${i}	/srv/castor/${n}	xfs logbufs=8,logbsize=256k,noatime,swalloc,inode64" >> /etc/fstab
	((n++))
done

Benchmarking a single disk

Cern ask for the first and last disks in the storage array to be tested and for each test to be run 4 times and an average be taken.

This benchmark can be scripted as follows: 

for j in `seq 1 4`;
do
	for i in {1,16}; # << Change 16 to the total number of drives being tested
	do
		/opt/iozone/bin/iozone -i 0 -i 1 -i 2 -R -I -l 1 -u 1 -r 1m -s 4g -F /srv/castor/"$i"/iozone.dat | tee -a iozone-1m-4g-single-disk-"$i"-loop-"$j".txt
	done
done

And then averages calculated: 

echo " "
echo "*** Results in KB/s ***"
echo " "
echo "1st Disk"
echo "=========="
echo " "
grep '  Read'  iozone-1m-4g-single-disk-1-loop* | awk '{sum=sum+$4; avg=sum/NR; printf "Average Read: %7.2f\n", avg}' | tail -n 1 
grep 'Initial write'  iozone-1m-4g-single-disk-1-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Initial write: %7.2f\n", avg}' | tail -n 1 
grep 'Random read'  iozone-1m-4g-single-disk-1-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random read: %7.2f\n", avg}'  | tail -n 1 
grep 'Random write'  iozone-1m-4g-single-disk-1-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random write: %7.2f\n", avg}'  | tail -n 1 
echo " "
echo "16th Disk"
echo "=========="
echo " "
grep '  Read'  iozone-1m-4g-single-disk-16-loop* | awk '{sum=sum+$4; avg=sum/NR; printf "Average Read: %7.2f\n", avg}' | tail -n 1
grep 'Initial write'  iozone-1m-4g-single-disk-16-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Initial write: %7.2f\n", avg}' | tail -n 1
grep 'Random read'  iozone-1m-4g-single-disk-16-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random read: %7.2f\n", avg}'  | tail -n 1
grep 'Random write'  iozone-1m-4g-single-disk-16-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random write: %7.2f\n", avg}'  | tail -n 1

Benchmarking all disks

Cern also ask for all disks in the storage array to be tested together and, again, for each test to be run 4 times and an average be taken.

This can be scripted as follows (in this case, with 24 drives being tested): 

for i in `seq 1 4`
do
	/opt/iozone/bin/iozone -R -I -l 24 -u 24 -r 1m -s 4g -F /srv/castor/{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24}/iozone.dat | tee -a iozone-1m-4g-24fs-loop-"$i".txt
done

For a different total number of drives, adjust the -l 24 and -u 24 values accordingly.

And then averages calculated: 

echo " "
echo "*** Results in KB/s ***"
echo " "
grep '  Read'  iozone-1m-4g-24fs-loop* | awk '{sum=sum+$4; avg=sum/NR; printf "Average Read: %7.2f\n", avg}' | tail -n 1 
grep 'Initial write'  iozone-1m-4g-24fs-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Initial write: %7.2f\n", avg}' | tail -n 1 
grep 'Random read'  iozone-1m-4g-24fs-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random read: %7.2f\n", avg}'  | tail -n 1 
grep 'Random write'  iozone-1m-4g-24fs-loop* | awk '{sum=sum+$5; avg=sum/NR; printf "Average Random write: %7.2f\n", avg}'  | tail -n 1
