Thanks. I didn't know about that; I'll give it a go.

Yep, I agree that the problem is the initramfs, but it *can* find all
the /dev/hd* entries, it has even created /dev/md* special files, what
it hasn't done is gone ahead and assembled the actual md devices that
those special files are meant to refer to (ie, running cat /proc/mdstat
shows no arrays). I'll check, but that sounds to me like the raid
personality drivers are loaded; there's just a step missing where it
assembles the devices... Unless mdadm loads the raid personalities when
it does its thing; I'll check that tonight.
Incidentally, this is software raid, not hardware raid.
Thankyou very much for your reply, but I don't think this is it; the md
devices can be created manually, no insmodding required.
Has the md raid system been deprecated in Gutsy? Is it likely that I
need to do something to migrate this to device-mapper or something?
I did think of another way to solve this problem, which I'll go to as a
last resort if I have to: do a new installation of Gutsy onto one of the
drives, copy the data across and then add the other drive as its mirror.
Something I'd like to avoid if possible though.
Thanks for your help,
James.
