I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this?

Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point.

Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process?

Thanks.
