I can confirm same issue here after upgrade or 14.04 to 16.04. Note that on my system, / is not on LVM.
lvm is not initiated at boot time nor at init time and the system gave up mounting /usr (/ is not on LVM on my system). For me, this is even worst, even when / is mounted and we are supposed to be in a sort of "userland", LVM is not up. I had to mount -- bind proc, run, sys and dev to /root/ Then lvm vgchange -ay then mount -a [This is required to run update-iniramfs as this script is in /usr and requires /var] Then mount -o remount rw / Then create a lvm2 script in local-top as described earlier [THANK YOU!] Then update initramfs with update-initramfs -k all -u Then sync and umount exit the chroot reboot This is not an obvious process to follow, especially ending up with an undocumented script in local-top :).
