lvm volume does not activate on boot

Binary package hint: lvm2

I have an LVM volume that spans two drives, I am not trying to boot off it or use it for /home, it is just additional storage. Since doing a fresh install of Lynx, I have been unable to get it to activate on boot.

The fstab entry is:
/dev/mapper/ds9-odo /media/odo ext4 errors=remount-ro 0 1

I tried following the instructions on https://wiki.ubuntu.com/DebuggingLvm, but as noted on that page, it doesn't seem to work on Lynx. scripts/init-premount/udev and /sbin/udevtrigger do not exist.

When booting normally, I always get the purple boot screen, with the message:

The disk drive for /media/odo is not ready yet or not present
Continue to wait or Press S to skip mounting or M for manual recovery

If I wait, nothing happens (waited several minutes)

If I skip, the system boots, and my lvm volume is unmounted.

If I use manual recovery, or skip and let it boot, and try a 'mount -a' I get:

mount: special device /dev/mapper/ds9-odo does not exist

If I run: 'vgchange ds9 -a y' in the 'manual recovery' shell I get:

File descriptor 8 (pipe:[4433]) leaked on vgchange invocation. Parent PId 886: bash
  1 logical volume(s) in volume group "ds9" now active

If I do it after skipping (once one the gnome desktop), I don't get the error, just:
  1 logical volume(s) in volume group "ds9" now active

Then, whether in the recovery shell or after booting, once it says ds9 is active, 'mount -a' works correctly.
