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. -Kanoa On Fri, 6 Aug 2004, Salyzyn, Mark wrote: > dd if=/dev/zero of=/dev/md0 bs=200b > > -----Original Message----- > From: linux-raid-owner@xxxxxxxxxxxxxxx > [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Derek Listmail > Acct > Sent: Friday, August 06, 2004 2:07 PM > To: linux-raid@xxxxxxxxxxxxxxx > Subject: Scrub? > > Many of the hardware raid controllers I've used have the ability to run > a > 'scrub' on an array.
