ok, I'm now some better performance out of my FC array. "vos move"
of a
4.4GB volume from one disk in the FC array to another disk in the
array
only took 16 minutes (4.6MB/s).
Derrick's suggestion of upgrading to 1.4.5 with namei did the trick.
Unfortunately, I don't think I can upgrade the firmware or tune the
3511
array. It's the 3511 expansion unit without the raid controller.
It's a
JBOD.
I think 1.4.5 and above has the no-fsync stuff enabled by default,
which really speeds up operations that do a lot of file creations/
deletions such as volume moves.
(if it doesn't, head over to the OpenAFS RT issue tracker and find the
patch)
