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

Need something like the following, replace <DRBD-backing-store> with
the appropriate device/partition:

 --- lvm.conf.orig       2010-10-01 14:01:59.350001934 -0500
+++ lvm.conf    2010-10-01 14:24:11.306001934 -0500

     # By default we accept every block device:
-    filter = [ "a/.*/" ]
+    filter = [ "r|/dev/<DRBD-backing-store>|", "a/.*/" ]
