Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Your lvm.conf is likely included in your initial ramdisk, and you
probably forgot to update that. Thus, your LVM volumes are probably
being enabled by the initrd, and this preempts DRBD.

Update your initrd, reboot, and see if the problem persists.
