1 ost-survey (OST performance survey)
2 ===================================
3 This script is designed to test the client-to-disk performance
4 of the individual OSTs in a Lustre filesystem. The network transfer
5 time from the client is included; to get a better idea of the isolated
6 disk perfomance, run this script on a client running on the OST.
9 $ ost-survey [-h] [-s <size>] <lustre_path>
12 <lustre_path> : mount point of lustre client
15 - Lustre filesystem is up and running
16 - Script is being run on a client
