wondering why you would want to do that other then checking to see if
there is something wrong with some chunk of hardware?
If you want to test the speed of the Lustre fs it really depends on how
many OSSs, OSTs (and OSTs per OSS) you have (and what other hardware
you're using) and how you set your striping depending on your
applications. Best performance will probably be N --> N worst
performance probably strided writes N --> 1. Also multiple access from
one client seems to slow stuff down.

Is there any way to benchmark the local filesystem performance of
Lustre on the OSS side? For example, I want to benchmark the random
and sequential I/O bandwidth of the local filesystem of Lustre 2.5 using
IOR.
Is there anyway to run IOR directly on its local filesystem without having
to go through the network?
Thanks!
