Hmmm. If your network breaks horribly, you will probably need to restart the daemons — once their communication breaks they'll start marking each other down and the monitors will probably accept those reports once the network starts working again. (Actually, maybe we should update that so the monitors reject sufficiently old reports.) But it will be a transient effect; restarting your machines will be enough to restore service. :) -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
