Description

When changing a LAGG from any mode to another mode while it has child interfaces that are something like VLANs and CARP VIPs on them will cause CARP to go to an init status and never recover.

If you re-save the interface or reboot the firewall, they will go back to MASTER or BACKUP (depending on if it's primary or secondary). This can be worked around by failing over manually before making these changes and rebooting the firewall you're working on to avoid disruption, but this seems like a bug that should not present itself.

Bug was present in 2.6 of CE and 22.01 of pfSense Plus.

Viktor,

When testing with a customer, they had several dozen VLAN interfaces (around 50). Likely this is needed to trigger this.
