Is there a detail step by step howto? The raid 1 has no LVM. just md0, md1 and md2. md0 is /boot, md1 is swap and md2 is the storage. I had replace sba with a new disk. I tried to boot up and it says kernel panic. How am i going to reconstruct the raid and sync sdb to sda?
You might find these notes http://ex-parrot.com/~pete/software-raid-howto.html handy- but I can't confirm they are 100% correct for you- you have to work that out yourself. If you have the ability to clone the surviving drive to another drive as an extra backup on top of the one you already have (of course you do?) I'd do that before potentially accidentally screwing up this disk as well!
