I've done some experimenting:
Yes the server was starting up with a SID of 0 which is why replication is
failing. After some testing I've discovered that if I use a hostname rather
than an IP address then the servers do get the correct SID at startup, and
do replicate correctly. Is this a bug or a missing note in the docs?
Additionally in my first attempt, the 2nd server has started up from a
minimal config, correctly replicated all the config, then the main DB from
the 1st server. It then continued to replicate across all changes to server
1. However any changes on server2 weren't applied to server1 until I
restarted server 1. Server 1 then caught up with the changes from server 2.
Since then every seems to be fine and everything is replicating in both
directions. Can I presume this is an oddity that I'll encounter the first
time I bring a new server online, or is something I should be more worried
about? My next step is to add a 3rd server into the mix.
