Well, for safety reasons I thought about something more sophisticated, a parser that understands the structure of drbdsetup's configuration data output and converts sections and attributes to a neat data structure that can be addressed directly. I will use the data captured for other things to, in this case (live migration) to determine the protocol before setting it to C, to be able re-set it after migration to its previous value. E.g. in case some VMs might use protocol B in the future, so after live migration I will set it back to B without having to call drbdadm adjust.
