Sorry, I only read the statements upon mkraid; the most reason why it
fails is the missing patch or the option to the command. This time it
was the patch not the option, which I guessed.
Benchmarking software is also available from www.uk.kernel.org for
example. Look at for Bonnie; a little program that benches I/O of the
devices with files of various size (you can chosse the size).
Greetings, Dietmar
