To late to convert to raid?

[romenyrr]

Well i know in windows i can convert the live drive to a dynamic drive, and then create the raid in just a few simple steps, but how can i do this in linux? is it possible to convert the hard drive fs type to to fd? how can i make sda2 and sdb2 into md0? is this possible? heres my current fdisk output:

Disk /dev/sda: 33.5 GB, 33554497536 bytes
255 heads, 63 sectors/track, 4079 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I haven't tried this but I would test it on some non essential data first.

Try contacting the mdadm maintainers at linux-raid@vger.kernel.org

Hi romenyrr,

Sorry that the guys were rude, they're usually pretty helpful!

Nice article you found, I was trying the same thing on a VM!

Hey, I've written my own guide on how to convert a single drive system to a mirrored setup using raid1 or raid10, geared a bit more toward debian and ubuntu users. You can find it here:
