I'd recommend allowing someone else to look these directions over, but I believe this will create your mirrored devices while preserving your data. I'm not terribly familar with LVM under Linux so again, I'd encourage you to let someone else look these steps over for correctness before using them. These are basically step by step commands that create a 2 new md devices for your 2 mirrored partitions, each mirror containing only 1 device. These devices then have your data copied over to them. After the data is copied onto the md devices, the additional disks are added. The md subsystem then takes care of syncing the mirrors automatically. mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda2 missing mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/hdc2 missing mke3fs /dev/md0 mke3fs /dev/md1 mkdir /mnt/md0 mkdir /mnt/md1 mkdir /mnt/hda1 mkdir /mnt/hdc1 mount -t ext3 /dev/md0 /mnt/md0 mount -t ext3 /dev/md1 /mnt/md1 mount -t ext3 /dev/hda2 /mnt/hda1 mount -t ext3 /dev/hdc2 /mnt/hdc1 cp -av /mnt/hda2 /mnt/md0 cp -av /mnt/hdc2 /mnt/md1 umount /mnt/md0 umount /mnt/md1 umount /mnt/hda1 umount /mnt/hdc1 mdadm --add /dev/md0 /dev/hda1 mdadm --add /dev/md1 /dev/hdc1 mdadm --detail --scan | head -1 > /etc/mdadm.conf You'll want to create the appopriate entries in /etc/fstab to ensure these are mounted at boot time. Also, you'll probably want to edit /etc/mdadm.conf to add the following above each ARRAY line: DEVICE partitions MAILADDR root At the end of each ARRAY line, you'll want to add the option auto=md -- this will force mdadm to create the appropriate md devices in /dev should they not exist at the time the mirrored volumes are found at boot.
