sure,
i have it attached. needs a little bit of "beautification".
I can't remember the exact raid configuration. i think it was raid5
across either 3 IBM uw's, or across 3 IBM's uw and a Seagate Empire
fn. i didn't wait for the resync to finish. (don't know significant
this is).
ck refers to chunk size, fs refers to filesystem block size.
the figures favour 4k e2fs block size in every case. so there's no
doubt about that one.
wrt to chunk size, the figures seem to peak at 64k.
