Thanks Kevin for your help on this.
Can I change a ext3 partition (sda1) with data on it to raid 0 or do I
have to do a fresh install ?
Look at the raid tools like mdadm. I'm pretty sure you can (mdadm
--assemble?), but you have to be careful of the options you use when you
create the raid array. Read the help files and the man pages.
caveat: I don't run RAID at home (nor do I use LVM anymore), but I used
to work for a RAID storage array company 7-8 years ago....
If I am not mistaken, writing the software RAID metadata to the existing
partition would damage the filesystem. Additionally, playing with the root
partition and the partition that contains /boot (in this case they are the
same) can very quickly render a system unbootable, as there are many potential
places where configuration changes would be necessary, including the boot
loader. Unless you have a strong attachment to the running instance, I
strongly recommend backing up your data and starting with a fresh
