First thing that comes to mind, you should look into setting the remote device
as --write-mostly, so that the local one is preferred for all reads (as long as
it's up).

But to be honest DRBD may indeed be a better solution for this use case, as
it's built specifically with it in mind, and likely has all the various
gotchas that might arise already thought about and handled properly.
