more RAID whoe's

[Gary Stainburn]

Hi folks.

Last week I added another drive to my backup server.
I then reshaped the RAID arrays and then resize2fs'd the main partition.

All looked fine until I rebooted, at which point it failed after loading the 
kernel.

Last time I got round this by upgrading from FC7 to FC8, during which time it 
re-installed the boot loader and installed the latest HDD image and all such 
*stuff*.

I tried this again, upgrading from FC8 to FC9, but this time it isn't working.

However, it didn't work but in a way I didn't expect.

My boot partition partition is mirrored on the 1st and 2nd HDD's as it always 
has been.  The boot loader then booted from the copy on /dev/sda1, and then 
remounted later as normal using /dev/md0.

However, now I get the following displayed on screen. It looks like the boot 
loader doesn't like the partition type - but this hasn't changed.  The splash 
screen and menu all appear on-screen so GRUB at least can see the /boot/ 
partition to do this. (The following were collected having booted from the 
rescue CD).

I have noticed that the mirror isn't symetrical either as there seems to be an 
extra partition (
Anyone got any ideas
