I wouldn't be worried about the dev/md3 partition being at 92%, that wouldn't cause your HA issues at all. If you are utilizing the dedicated HA1 and HA2 ports and not configuring another interface as a high-availability interface, high dataplane utilization shouldn't cause the HA interfaces to drop out. I would open a ticket with TAC so they can look at the associated logs and see exactly what was going on at the time the interfaces dropped.
I'm seeing the same issue here. We have an active/passive 5250 cluster.
We are running PANOS8.1.9
All HA links are directly connected.
cluster node 1:
cluster node 2:
Is this a known issue?
Did you ever find a solution to the issue you mentioned? I'm currently running into a very similar issue with a 5050 active-passive cluster running on PAN-OS 8.1.10. We've been working with TAC for the past few days and haven't had any resolution. Any info would be much appreciated.
As it only happened once we closely kept monitoring the cluster behavior in case it would re-occur...but it didn't. No support ticket was opened.
I will keep you posted if it happens again. We are still running PANOS 8.1.9.
Please let me know the outcome of the support ticket.
