Hi Max,


You didn't say, can you configure the carp interfaces by manual
ifconfig?
That would indicate a problem in the netstart/rc.d part. Maybe
mergemaster again?

I get an error when trying to configure it manually via ifconfig. I
don't know what this means.

test# ifconfig carp0 create
test# ifconfig
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet 10.1.0.201 netmask 0xffffff00 broadcast 10.1.0.255
ether 00:30:48:11:64:85
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
fxp1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
ether 00:30:48:11:6f:68
media: Ethernet autoselect (none)
status: no carrier
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet6 ::1 prefixlen 128
inet 127.0.0.1 netmask 0xff000000
carp0: flags=8<LOOPBACK> mtu 1500

and then:

test# ifconfig carp0 vhid 801 pass mekmitasdigoat 10.1.0.101/24
ifconfig: SIOCSVH: Invalid argument


From 'man ifconfig' - Looks like your vhid must be from 1 to 255, so 801
is probably what's breaking it.

The following parameters are specific to carp(4) interfaces:

advbase seconds
Specifies the base of the advertisement interval in
seconds. The
acceptable values are 1 to 255. The default value is 1.

advskew interval
Specifies the skew to add to the base advertisement
interval to
make one host advertise slower than another host. It is
speci-
fied in 1/256 of seconds. The acceptable values are 1 to
254.
The default value is 0.

pass phrase
Set the authentication key to phrase.

vhid n Set the virtual host ID. This is a required setting.
Acceptable
values are 1 to 255.

Regards,

Mike
