Software RAID on an existing system
I have a linux server running, and it doesn't have raid.
I'd like to setup raid 1 on it.
Is it possible to take my existing server, add another HD to it and set up raid 1 so that non of my data would be lost?
Or would it be better to just add two new HDs and setup raid 1 on them and mount them? Then put my important data on the raid mount.
I'd really just like to take my existing server and setup RAID 1 with the existing disk.
I'm thining its not possible though.
Anybody have any thoughts, ideas?
