You will need to change this to something like (as taken from man carp):
match system CARP;
match subsystem [0-9]+@;
match type(MASTER|BACKUP);
The subsystem now is generated as
snprintf(subsys, IFNAMSIZ+5, %u@%s, sc-sc_vhid, sc-sc_carpdev-if_xname);

Thanks for the info. I was able to get the triggers firing from devd. I also
noticed that the man page on 'carp' references a carpcontrol.sh script as an
action. Has this script been prototyped anywhere yet?

Mind posting the devd.conf entries you are using? Maybe submitting a
docs PR with them included, to update the HAST page?
Thanks. I haven't played with HAST and the new CARP code yet.

The entirety of the cogent entry in /etc/devd.conf that I am using follows;
notify 0 {
match system CARP;
match subsystem [0-9]+@;
match type(INIT|MASTER|BACKUP);
# action /root/carpcontrol.sh $subsystem $type;
action /etc/test_carp.sh $subsystem $type;
};
This differs from the example in man 4 carp only by one line. I substituted
the 'action /etc/test_carp.sh $subsystem $type;' for the line above it, as I
cannot seem to locate a 'carpcontrol.sh' script anywhere on my 10.0-CURRENT
test platform. Hence my earlier inquiry as to if it had been prototyped
anywhere yet. I did locate several CARP related action scripts in
/usr/share/examples/hast/ but I'm not sure how they different from this
ephemeral 'carpcontrol.sh' script without seeing it.

I can't seem to create a carp interface despite having compiled a

interface fail; # ifconfig carp create
ifconfig: SIOCIFCREATE2: Invalid argument
From what I've read in the handbook entry on CARP
(http://www.freebsd.org/doc/handbook/carp.html), I should be able to
either compile in the carp device, as above, or load the if_carp.ko
kern module. There doesn't appear to be a if_carp.ko module in the
-CURRENT source tree, however. Only the carp module itself;
# ls -ald /usr/src/sys/modules/*carp*
drwxr-xr-x 2 root wheel 512 Dec 27 15:12 /usr/src/sys/modules/carp
Am I missing something completely obvious? Was the functionality of
if_carp.ko rolled into another module?
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.
