[mythtv-users] When is the master BE not the master BE?

[Brian Foddy]

A month ago, I swapped out my master BE machine with another,
doing so changed the machine name and IP address.

To do the conversion, I dumped the database to a file and
globally changed every occurrence of the old machine and
ip address with the new values, copied it over and reloaded
the database.  Then I double checked the values in 
mythtv-setup and everything seems fine.

The system also has a slave BE machine that doubles
as a FE machine, which hasn't changed names/ip.

The system is working fine except for two funny 
problems.
1.  It refuses to run mythfilldatabase automatically as the
old master used to do.  Manually running it works fine.
2.  The system is not logging any events in the database log.

Beyond that, it schedules programs, plays, etc just like it's
supposed to.  The slave machine also works like it should.

I'm running 0.20.1 on a Mandriva 2007 Spring machine.

Must be some setting I've missed in the conversion, but
can't find it.  Any clues?
