Mismatch in the number of CoreXL FW instances on new 3800 cluster, but no mismatch can be found.

[Dan_Currens]

Two 3800 gateways running in a cluster on R80.40 Jumbo 125.

Node "A" in the cluster /var/log/messages full of:

fwk: CLUS-114802-2: State change: DOWN -> STANDBY | Reason: There is already an ACTIVE member in the cluster (member 1)
fwk: CLUS-113900-2: State change: STANDBY -> DOWN | Reason: Mismatch in the number of CoreXL FW instances has been detected

The cluster will not failover to this node.

Tried forcing the number of CoreXL instances to 6 in CPCONFIG and rebooting.

Tried removing nodes from cluster and re-adding.

Any suggestions?

Cluster does show as a healthy cluster in cphaprob stat:

License looks correct CPSG-C-8-U

Hi, i had an similar issue but that was by using wrong license..

However, i tried as you to change in cpnconfig/corexl but it did not help and i ended up disabling corexl, reboot and then enable again and after that it worked.

Hi @Dan_Currens 

You also see the following message "CLUS-114802 There is already an ACTIVE member in the cluster (member X)". But that should be ok.

I would do the following:

1) Reboot both gateways

2) Check if dynamic split enabled
     # dynamic_split -p
    In this case, I have also seen various errors. If necessary, I would disable dynamic split.
    
3) Install the latest R80.40 JHF 139

[AmitShmuel]

Dynamic Balancing does not change the number of loaded FW instances, only activates/inactivates if needed, which does not create a mismatch.

It does require the maximum number of FW instances to be loaded, but this should be configured on all clusters members.

Please open a TAC case for this.

Would appear to be some kind of bug since your CoreXL split is identical on both members.  However do you have another separate ClusterXL cluster running R80.10 or earlier on the same VLAN(s) as the problematic cluster?  Wondering if it could be a Magic MAC issue with an older cluster present, as Automatic MAC Magic was not introduced until R80.20.  Make sure that Automatic MAC Magic is enabled on all your clusters that support it with this clish command: show cluster mmagic

Also:

Cluster failover count:
Failover counter: 3007

Your cluster is flapping like crazy, TAC should probably be engaged here to see what is happening.

[Dan_Currens]

That was it, there was another old cluster in the same VLAN .  Thank you for your reply.
