+ENVIRONMENT VARIABLES
+---------------------
+BTRFS_SKIP_LVM_SNAPSHOT::
+	Controls if the *lvm snapshots* have to be
+	ignored. Default "yes"; if you need to consider them, set it to "no".
+	Pay attention that *btrfs* may be confused if two devices have
+	the same dev uuid. This is the reason to skip a lvm snapshot.
