I added two 320G drives to my server, configured as RAID1. I previously had a RAID1 setup of two 120G drives. Unfortunately I don’t have enough drive bays & power connectors for more than 3 drives, so I had to remove one of the 120s. After some manual editing of the partition table and deleting the old RAID device, I converted the remaining drive to a bootable ext3 root file system without losing any data. To do that, I used fdisk to change the partition type from raid autodetect to linux (83). The new 320G RAID is mounted as /home. I’m now in the process of copying the data from the old home directories.
