Just to clarify, the configuration I was referring to was supposed to have a master and slave DNS server for private zones (only two DNS servers) but something happened during/after upgrade and they both showed master (actually rndc -s 127.0.0.1 -r zonestatus <zone - both forward and reverse for all zones>) reported master and the other primary.

So somebody referenced this KB article because presumably it was tangentially relevant, but I don't know that the OP is working with standby infrastructure (good question!). All they say is that after an upgrade all servers were masters. The amount of direct relevance of the article is questionable. Nonetheless, paragraph two seems factually incorrect on its face: changing type master; to type slave; does not swich a server from secondary to master, last I checked it did the opposite.

All examples (barring questions of relevance) of configuration syntax in the article specify a file statement. In one case it's implicit as in masterfile-format raw; and in the other it's quite explicit (but both of the examples are talking about standby primaries, which are not an explicit thing in the software although they are conceptually understood). Please re-read the second paragraph and try again. > If the server currently being secondary for "example.com" does write that > zone to disc then it is easy to switch it to become primary because it > already has the zone file stored locally.

No. I have personally set up and administered a corosync / pacemaker cluster to do a standby to master promotion (for publishing RPZs with BIND) in a past life.
