Either hde1 or hde is definitely in use by something else.
Try:

That's what you get for using rh and their nash ;)
What IS /dev/root? How does your root device
is specified in initramfs -- by uuid/label?
I bet it is running off /dev/hde1, not /dev/md0.
But this does not explain why it can't add
/dev/hde3 to md1.
Speaking of "LVM is not in use" -- I understand
it like "you didn't set it up", but are you sure
it does not stay on the way? Like, the dm modules -
how about rmmod'ing them?
In any way, if nothing obvious comes on, your best
bet is to booting into single-user mode, stopping
all "extra" processes, umounting everyhing that's
possible, and trying mdadm from there.
Or from initramfs itself, if that has any tools in
there.
