OST-SURVEY:
This script is designed to test the client-to-disk performance
of the individual OSTs in a Lustre filesystem. The network transfer
time from the client is included; to get a better idea of the isolated
disk perfomance, run this script on a client running on the OST.
For syntax and other information please see help and
README.ost-survey file in the same directory for this tool.
