Current CARP demotion level -240 on Master and Backup

[bsdhob]

Hi,

on both Master and Backup the current CARP demotion level is currently -240. I'm also getting the warning:

CARP has detected a problem and this unit has been demoted to BACKUP status.
Check link status on all interfaces with configured CARP VIPs.

What could be the reason for this problem?

Communication between master and backup is broken on at least one pair of interfaces.

How can I test the CARP IPs /connection? By pinging them from the Master and Backup?

I verfied that all interfaces are up on both firewalls and all CARP IPs are pingable.

The log shows the message:

carp: demoted by -240 to -240 (pfsync bulk done)

Sync Ips are working fine.

Is it recommended to use the Multicast IP or the Configuration IP for the Sync IP?

I've run into that -240 demotion issue before, and it usually points to a problem with the interface links for the CARP VIPs. It's a good idea to check if all the interfaces are up and stable. I found that looking through the logs can help identify any interface flaps or errors that might be causing the issue. When I had similar problems, restarting the CARP services on both units did the trick for me.

All interfaces are up according to the GUI overview. How can I check the CARP VIPs interface status? The logs never revlead any severe problem.

How do you manually restart the carp services?
