I've recently just been getting into this mdraid stuff as I
rebuild/upgrade some hosts. During my experimentation, I did find that
you need the arrays to be defined in /etc/mdadm/mdadm.conf for them to
automatically build - and of course you need to update your initrd after
making any changes.
ARRAY /dev/md/main metadata=1.2 UUID<your array UID> name=<your array
name>
I believe /usr/share/mdadm/mkconf shoudl make this automatically for
you.
I spent a bit of time at a busybox prompt figuring this out ! But don't
take my word, I'm only a novice at this. In my case I didn't upgrade
from Lenny, I just wiped the storage (it was previously hardware raid,
and I upgraded disks) and did a fresh install of Squeeze.
I had this problem because I manually created the arrays before starting
the installer, because the installer doesn't seem to give you the
opportunity to name the arrays etc. So of course, because the installer
didn't build the arrays, I think it just missed the step of creating the
correct config file.
