If I configure all carp interfaces via command line (removed the hostname.if carps) after machine is rebooted this "problem" doesn't happen ! :O This is crazy and I'm out of ideas for now. I was playing with carpdemote and state transition from master to backup and vice-versa works fine. It's something I can live with (nodes aren't to be rebooted all the time) but not 100% satisfied :)
I will try to do some tests with different hardware so I can finally blame this on hardware hehehe Thanks, John > > I wonder if this could happen if broken interrupt routing means the > backup doesn't see all the carp multicasts coming from the master, > so you have multi-master and the firewalls fighting... > > IME, with H8SSL-i (not i2, but they are fairly similar) the onboard > NICs don't co-exist well with some PCI NICs, I disable them (there's > a jumper on H8SSL-i)... > > Also you mentioned unpatched 4.2 and pfsync, it doesn't affect this > problem, but you most certainly do want the patch to fix erratum 004 > if you run pfsync. Several of the others are worth having too.
