There's no need to use RAID for swap, it's not like it contains anything of permanent importance. Create a swap partition on each disk and let the kernel use the space as it wants. > The relevant advantage of btrfs is being able to make snapshots. Is > that worth all the (potential) trouble?

It can still warn you of corrupt data but it cannot fix it because it only has the one copy. > Well, then they need to make special provisions for swap files in btrfs > so that we can finally get rid of the swap partitions. I think there are more important priorities, its not like having a swap partition or two is a hardship or limitation. -- Neil Bothwick Being politically correct means always having to say you're sorry.
