RE: CARP on -CURRENT

I much appreciate the responses and I was able to get CARP functioning using the new ifconfig syntax under -CURRENT. Having done that, CARP is now acting as it should, though now I have a new challenge with devd and automatic firing of scripts during CARP failover. It appears that the documented method of doing this at http://www.freebsd.org/doc/handbook/disks-hast.html no longer works with the suggested devd.conf setup;
notify 30 {
	match "system" "IFNET";
	match "subsystem" "carp0";
	match "type" "LINK_UP";
	action "/usr/local/sbin/carp-hast-switch master";
};

notify 30 {
	match "system" "IFNET";
	match "subsystem" "carp0";
	match "type" "LINK_DOWN";
	action "/usr/local/sbin/carp-hast-switch slave";

Is it likely that the triggers associated with CARP for devd have changed due to the recent new CARP overhaul? Does anyone know what the new triggers may be?

Love,
Andrew

You should definitely read this changeset:
http://svn.freebsd.org/changeset/base/228571

and the updated carp ifconfig syntax in man carp. As for if_carp.ko, it was renamed into carp.ko as part of the CARP implementation overhaul.

This only affects CURRENT.
