Relating to this tutorial :
I have a question - I have set my system up following your tutorial, but wanted to upgrade to Ubuntu 8.10. My /boot partition was too small at 50Mb so I used the Live CD to resize it to 200Mb, deleting the /dev/sda2 partition in the process.
How do I resync the RAID array to bring the recreated /dev/sda2 back into the RAID? It says /dev/md0 is not started when trying to do it from the Live CD, and booting from the actual system itself I cant do it either as I am unable to mount the RAID mount as it is in use by the system!!
