RE: Scrub?

Eh, that would delete the contents of the array, including the
filesystem. Is that what you meant by "scrub"? I thought "scrubbing"
meant looking for unreadable blocks and pro-actively replacing them
from parity. The latter would be very useful for a software raid 5
array since there is currently no facility in software raid for doing
this on-the-fly. I imagine it would be possible to write such a
utility in user space. I, too, wonder if anyone out there has
something that works.

Subject: Scrub?

Many of the hardware raid controllers I've used have the ability to run
a
'scrub' on an array.  Is there a way to do this on a linux software raid
5
array?
