I think this post would benefit from the distinction between the three
major abstractions in LVM: physical volumes, volume groups, and logical
volumes.
You want to use DRBD to either replicate entire PVs (thus replicating
entire volume groups, with all their LVs), or individual LVs.
If you have one Logical Volume only containing the entire system as a
single file system, yes, that is probably not what you want to
replicate.
