It's recommended to use a script to scrub the raid device regularly, to detect sleeping bad blocks early.What's the best way to do that? dd the full md device to /dev/null?echo check >/sys/block/md?/md/sync_action Distros may have cron scripts to do this "right". And you need a fairly recent kernel.
Does this test stress the discs a lot, like a resync? How long does it take? Can I use it on a mounted array? -- -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS d--(+)@ s-:+ a- C++++ UL++ P+>++ L+++>++++ E-- W++ N o?
