not sure about the LVM side of things (fix the raid bit first
hopefully).
I would guess, that you didn't do a update initrd, thus the mdadm.conf
on your initrd is the old one with the 3 disk raid 5 instead of the 4
disk. fix that first, then on reboot append to the kernel boot option
init=/bin/bash.
This will drop you out of the process before everying thing else
happens, you should have root mounted. Check your md's make sure they
have come up okay first.
as for the lvm you might be lucky if lvm hasn't started because of the
error then you might not have lost anything.
