OK, if it's RAID-0, it's striped, not mirrored, and you have NO redundancy at all. If either of those disks fails, your SOL. If it's mirrored, you meant RAID-1. I might have let it pass, but if you think you're mirrored (RAID-1) and are striped (RAID-0) instead, you could be in for one NASTY surprise if one of the disks dies. So I thought it wise to post and warn you, just in case it WASN'T just a typo and you screwed up, BEFORE something happens and you lose the data. But you're correct about swap, at least if you have them set at the same priority. The kernel will automatically stripe across all swap partitions set at the same priority, so if you have multiple disks, put a swap partition on each and set the priority equal (in fstab if you automate swap loading from there), and the kernel will automatically stripe them, increasing your swap performance accordingly. =8^) -- Duncan - List replies preferred.
