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