Is it possible to partition a disk with Disk Druid and control the order of the partitions? I want to create my own boot and swap as RAID partitions but Disk Druid won't keep them in the order I want, no matter what I specify first. I've done this before by using fdisk to make the partitions before starting Disk Druid but I thought someone said this was an old bug and should have been fixed.

I don't know the answer to your question - but I know a question you might want to ask yourself - why am I doing this?

Two choice quotes:
1. There's no reason to use RAID for swap performance reasons.
2. There has been a lot of discussion about whether swap was stable on RAID devices. This is a continuing debate, because it depends highly on other aspects of the kernel as well.

Well, the reasoning about the kernel being able to find stuff in swap if the partition was mirrored kind of makes sense. Where I work, we used to put use two separate partitions for swap. Whenever a disk went down, the box was likely to crash too and so we would find out about the disk after a reboot. After we made those partitions a mirror of one another for swap, we now don't get crashes and we get notifications of a disk going down.

I have machines that are still running that have survived having the drive containing one member of a mirrored swap partition replaced (they are hot-swap SCSI's). Odd you should mention the stability issue though - earlier instances were uneventful but the last time it happened several process died including crond. I suppose I should have rebooted, but I haven't yet. After rebuilding and restarting a few things it has been stable since (about a month now). I wonder if I was just lucky the other times or if it is no longer handled correctly in the kernel. Does someone think it isn't important?
