I want to set up a server using software RAID1 as follows: - Install single disk, do the OS install (Ubuntu server 11.04), creating RAID array (but degraded as only one disk) - Boot the system and check it all works - Install second disk and add to array
The install works fine (I create an md partition and an array of 2 devices but only add one to it), and install grub to /dev/sda1 as usual.
However it won't boot. Grub starts and gives me my menu, but gets no further.
Suggestions? Am I doing this all wrong?
(Reason for doing this: migrating an existing RAID1 array using the onboard RAID to an mdraid array; I want to keep one of the original disks to recover some files off once the system is up before wiping it and adding it to the new array. But also I want to confirm that my new array will boot with only one disk otherwise there's not a lot of point to it!)
