I'm hoping an actual expert will respond to your question and educate us all, but in the mean time I had a thought: is device-mapper starting your volume groups on both systems, and then the LVM resource agent script is correctly noticing this?
Maybe you need to configure LVM not to start automatically and instead wait for the resource agent script to do it.
