Looks to me like that is already the case (Server 1 is has advskew 0, Server 2 has advskew 100). > Also, we used to have something like 20 for master and 80 on slave so one > can place slaves before master, or master after slave if you want to signal > "I am still running but would like to hand over to the other if we can". The carp demote counter is also relevant to failover and is sometimes raised at run-time when interface output errors occur. The advskew value only matters as long as the demote counter is equal on both sides. See 'ifconfig -g carp' and the 'carpdemote' directives documented in the INTERFACE GROUPS section of the ifconfig man page. To avoid potential routing issues, I would recommend setting netmasks to /32 on all carp interfaces if they share a subnet with an Ethernet interface. I have no idea about a possible specific reason for packet loss, though.
