1 This script is to be used to test the performance of the
2 individual OSTs in a Lustre filesystem.
5 - Generate a fixed amount of IO per OST
6 - Identify the fastest and slowest OST
13 Identify number of OSTs in system
16 - use lfs setstripe to restrict IO to that directory
20 - Lustre filesystem is up and running
21 - Script is being run on a client
26 0. Check pre-requisites
28 1. Identify the number of OSTs in the system
31 2. Collect input parameters
34 3. Set up array to hold output
38 - Set striping on that directory
39 - Run some IO and time
43 5. Determine max an min for the array
