Comment "Scrubbing" Arrays in Linux (Score 1) 649

I've recently build myself a "Poor Man's RAID Array" out of 8 x 300GB drives in software RAID5. After reading about Sun's ZFS, I'm wondering if there's a way to do something similar to their "disk scrubbing" with Linux's md raid.

Basically run through the array and check each stripe against it's parity, and re-write (to attempt to fix) the stripe if it doesn't match.

At least it's something to think about, since two disks could get a small error, each on seperate parts of the disks, and then the RAID5 rebuild could fail when you try to rebuild it after a disk fails, even if there is enough data to reconstruct the missing parts.
