One logical volume active, one not in initramfs

[Ross Boylan <rossboylan@stanfordalumni.org>]

I have a VM that won't boot because it can't find the root device.  The system (Debian 7.9) uses a volume group "markov02" with 2 volumes, root and swap_1.  In busybox ls /dev/markov02 shows only swap_1, although lvm lvs lists both.  vgchange -ay says it's is activating 2 volumes, and afterwards ls /dev/markov02 shows both of them.

Any ideas what's going on?

Thanks.

P.S. Is there an official way to tell which logical volumes are active?
