# iops.sh lists all physical volumes in the system sorted by IOPS, so you can
# identify who is the most demanding disk/s device. It also shows Physical#
# volume name, Volume group name and mounted file systems belonging to that
# volume group.                                                                 #
# It is an excellent tool for troubleshooting Disk and file system over-loads.   #
# It also shows the system total IOPS. 
# Enjoy!
