Ok i actually found a site with a bit more info. Here is what i found, going to try this next maintenance window. Make sure you have a backup when your trying this. Maybe even a backup of your backup.
Code:
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda3 /dev/hdc3
Explanation: This creates a mirror named md0 comprising of /dev/hda3 as the main partition to be mirrored and /dev/hdc3 as the miroree. Note: I'm sure doing the root partition is a bit more painful, but i will see when i drop it into single user mode.
After the mirrors are created check them using this command:
Code:
watch cat /proc/mdstat
Wait for the disks to finish syncing and then make the entry change in /etc/fstab. Change /dev/hda3 to /dev/md0 for example. Trying to find more info about mirroring the root partition now. Any thoughts or suggestions fire away.
