I was wondering if this procedure (swapping on Raid1 + waiting for the resync),
is safe on an IDE only system ?
I don't need hot-swapping, the only thing I need is that if one disk dies,
swapping will not take down the disk (hangs like in the SCSI case etc).
If this is safe I can easily live with the "wait for resync" issue.
