Here's a few blockings.. -- This happened very shortly after starting the
recording, so I'm not 100% sure this is the typical blocking I see, I'll
post another dump when that comes up. This has your extra printout and
this mornings svn version 7830.
file: linuxis.us/dump3.blocking : Blocking IO is 3/4ths the length down,
1k lines.
I'll only post one set of hdparms, since all the settings are identical on
each drive (I've checked this a dozen times so I know they're synced.
