You can also use Heartbeat for the master/slave, with a haresources file
looking like "mfsmaster IPaddr::192.168.0.100/24/eth1 switchMFSmaster", and
creating a script switchMFSmaster launching the following lines when
switching from slave to master :

        mfsmetalogger stop
        mfsmetarestore -a
        mfsmaster start

And on the master node becoming slave :

        mfsmaster stop
        mfsmetalogger start

I agree with you, it would be really nice to have an integrated way to do
so.
