I have a home server, running Linux, which has a 2-disk software RAID1 device mounted on /. I recently had to replace one of the disks, so I removed the faulty one, put in a new one and added it to the array.

Since the RAID device is the root filesystem, is that all I need to do, or do I need to restore any special bootable stuff?

after the raid is done rebuilding, you might have to install grub to the second drive usually grub-install or in grub console root (hdX,Y); setup (hdX) are enough

Thanks. I had to research a bit on how to find the X and Y, but that's ok since I now understand more about the MBR and how Grub works. – Bart van Heukelom Sep 2 '10 at 19:01
