RAID on a Remote Debian Box

August 24, 2005 on 10:11 pm | In Sysadmin |

I am addicted to RAID. If there are 2 disks in a computer - there needs to be at least 1 RAID partition. If there are 2 identical disks - well then it almost begs to be a full RAID1 - grub, root, home, swap. If this box is a server - then it is a must.

The fun part is doing this on a remote box to which you have limited physical access. And by limited I mean - you can call a guy who may or may not be able to read the console and push the reset button when you can’t boot.

So I decided to do this… and I took some notes… I added a some comments, but otherwise it is a complete no-fluff doc of commands and output you should be seeing to get a non-raid system moved a raid1 with grub, root, home and swap ready for a failure of one disk.

The tricky bit is initrd and grub config, but I got it working in a couple dozen or so commands.

Hope this helps.
