I am not sure if this is your problem, but I would suggest to 
tell lvm2 to ignore the raw devices and to scan only the drbd
volumes. See 

https://docs.linbit.com/doc/users-guide-84/s-lvm-drbd-as-pv/

for example. On my hosts I have set global_filter instead:

diff --git a/lvm/lvm.conf b/lvm/lvm.conf
index 1b7ad9a..38137fe 100644
--- a/lvm/lvm.conf
+++ b/lvm/lvm.conf

     # above. Devices that fail the global_filter are not even opened by LVM.

+    global_filter = [ "a|/dev/drbd|", "r|.*|" ]

Hope this helps. Regards
