I gather you mean in this situation the raid doesn't need to be deactivated.

Going on what you said before the /etc/conf.d/rc variable should be set to RC_VOLUME_ORDER="lvm" if you are using raidlvm.  There is a bug in the /lib/rcscripts/addons/lvm-stop.sh which assumes that mount returns the symbolic link /dev/[volume group]/[logical partition] but it actually returns the actual device /dev/mapper/[volume group]-[logical partition].  The following path patch fixes this.
