[Lustre-discuss] Questions about benchmarking Lustre's local filesystem

You can use obdfilter-survey to profile performance of an OST similar to
the way Lustre would be reading and writing to the OST in production. You
cannot run benchmark programs like iozone or fio on an OST. You could mount
an OST device as an ext4 filesystem and benchmark that but it would not
operate like Lustre does so the benchmark would be somewhat pointless.

obdfilter-survey can use the obdecho kernel module on the OSS so you can
benchmark local Lustre performance without using the network.

obdfilter-survey comes with the lustre-iokit rpm package.
