Re: raidframe with R5/RS not reconstructing?

sorry, I meant iostat -x

Running any single iteration of 'iostat -x' yields:

each time.  Not sure why "wd8" seems to have such high transfer, unless
these are average statistics (I 'dd'-ed the whole disk to /dev/null as
a sanity check before attempting reconstruction).

Running 'iostat -x -w3' shows all but the system disk idle after the
initial display.  Forcing activity (again with 'ls -R') yields typical
output like:

wd8 is usually idle, but sometimes isn't.

Thanks.
