Greetings-
I have access to some virtual pfSense 2.0-RC1 hosts that need to be
upgraded to the latest RELEASE. All hosts are setup with CARP, but it
appears some of them do not have any slave systems. Meaning, of these
systems, there are some that are setup as CARP masters for various
IPs/VHIDs, but there are no systems setup as slaves for the same
IPs/VHIDs, at least not that I can find or have been provided access
to. I cannot disable these hosts to check for failover on the network
due to them being in production. Is there any way to find out if
there
is another host on the network interacting with a host doing CARP?

I guess you could tcp dump on the sync interface.
Or set the advertise frequency to something really high. If it switches
to slave there is somewhere a higher priorised slave which became
master.
However a lot people are running CARP VIP's simply to get a virtual IP.
As the note at the bottom of the page says:
Proxy ARP and Other type Virtual IPs cannot be bound to by anything
running on the firewall, such as IPsec, OpenVPN, etc. Use a CARP or IP
Alias type address for these cases.
Before IP Aliases where available only CARP allowed services on the
pfSense itself to bind to the virtual IP. If these installs are upgraded
from 1.x.x it's quite possible this is why.
