Not all rescue environments have MAKEDEV or have it in $PATH, so this should always work. ;)

Really, on my hp's as well? I don't have any /dev/hdx or /dev/sdx on the ones with software raid...

Nothing is easier than simply: # mdadm --detail --scan --verbose > /etc/mdadm.conf

And that actually *does* work in all environments...

Does that create the /dev/md* devices? I mean, a *scan* shouldn't change the filesystem, should it? That's the problem that line tries to fix: that there's no mdX device in /dev...

I think after adding those details to your mdadm.conf and restarting your /dev/md* devices would be created?
