1 ost-survey.pl (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
19 plot-ost.pl (OST survey graph)
20 ======================================
21 The plot-ost.pl script can be used to plot the results from the
22 ost-survey script using gnuplot.
24 Syntax: $ ost-survey /mnt/lustre > ost_log
32 Some sample test results:
33 Ost# Read(MB/s) Write(MB/s) Read-time Write-time
