Recovering Software RAID Mirror
 

Currently I have the setup below for both of my IDE drives.

SEAGATE 160GB HDA
148.4GB HDA1 mounted as /
600MB SWAP

SEAGATE 160GB HDC
148.4GB HDC1 mounted as /
600MB SWAP

I want to be able to boot from either of these drives due to them being mirrored. Right now I can bootup fine with the setup shown above, but when I take HDC and place it on the primary controller so it becomes HDA it doesn't boot. I want the RAID to be like mirroring in Windows. If your primary drive fails you can shut down the system, place the secondary drive on the primary controller and bootup. It's that easy with Windows. How can I achieve similiar results with a software mirror in Linux?

thanks

Do you even have RAID setup? If they are properly setup as RAID, you shouldn't even have to swap the drives in some cases... more details get better replies.
