For a three drive raid5 array, create one partition on each drive that is the same size (and doesn't overlap enything else!). It looks like you only have two unused drives -- that's fine. Create a raid5 array sdbX and sdcX and one "missing" drive (where X is the partition number you just created.)
copy over your filesystems, (if you're using an initrd, make sure it will detect your array) and boot off of your md array.
Now add your the partition that was in use to your array and you're set.That is a general overview of the steps, I'm sure more details can be found with google, and I strongly suggest you use mdadm, and scrap the raidtools package.

That is the way it was recommended by the software to have a whole disk partition. I am okay with the data. I have it someplace else too. So how should I have my partitions set up? Get rid of the overlapping partition....I am getting that.......so I should just have a Linux and swap partition.... So what partition should I be looking at raiding..... the Linux partition? What should I have put in my raidtab where the question marks are? I had a 3 for the whole disk. I am assuming that I should just do the Linux partition.. Should my first device be my hard drive at 0?

Then you create a filesystem on that and then put data in the partition.Sorry, I hope you didn't have anything important on that drive, and that you had backups.Mike Huston wrote:guess my formatting didn't stay....Device flag Start End Block Id System /dev/sda1 0 17000 1708000 83 Linux /dev/sda2 17000 17272 278528 82 Linux Swap /dev/sda3 0 17272 17686528 5 Whole diskThat is what I get for getting in a hurry...... ----- Original Message ----- From: "Huston" <shuston@ohiohills.com> To: "Mike Fedyk" <mfedyk@matchmail.com> Cc: <debian-user@lists.debian.org> Sent: Tuesday, November 02, 2004 8:14 PM Subject: Re: raidHere is how it is when I hit "p" after putting in the disk and entering the partition a hard drive command.

You can tell me if they are wrong, but that is how I have them I probably should put my swap at the beginning of the drive.
