      We have multiple VLANs with CARP enabled and they all work fine except for one. I've checked the interface IP / netmask settings, the VIP settings and the CARP settings and can't see anything wrong.

      Symptoms: CARP status on Master looks fine (all interfaces are shown as "MASTER", but on Secondary, Status for the interface is blank instead of "BACKUP". Please see screenshot below:

      Any ideas where I can look to see what's wrong?

        Look at the ifconfig output for that interface on both nodes and see what doesn't match. Post them both if you can.

        You might have a mismatch in interfaces between the nodes.

          Thanks for the quick response Derelict! I tried to paste the output here but it gets flagged as spam so I can't post.

          Instead I've uploaded the image to dropbox and hope that works:

            I was able to resolve this with a reboot today. I had previously tried that but no success, so that's weird. Not sure what changed, but at least it's working now.

              Right. There was no CARP VIP on the secondary.

              A simple edit/save of that VIP on the primary should have taken care of it.

              Perhaps XMLRPC sync was not working/connected at the time that VIP was created or something else anomalous happened.
