Strange behaviour after upgrading from 10.2.3 to 10.2.4
We've started upgrading our 2 BigIP from 10.2.3 to 10.2.4...
Everything was ok before on 10.2.3.
Unfortunately, we are getting a strange result... Here's the story:
Upgrade from 10.2.3 with HF1 to 10.2.4 on LoadBalancer 1:
Here's the status before applying the update to LB1 but I had the same problem doing it on LB2 to test:
LB1 (10.2.3) Active - LB2 (10.2.4) Standby
Step 1: Boot LB1 on 10.2.4, LB2 go in Active, GUI console and ssh available
Step 2: LB1 finishes its reboot go in Active (GUI console an ssh available) BUT LB2 stays in Active mode and strange part is that GUI console and ssh becomes unavailable on LB2 ("The remote system refused the connection").
Step 3: Connecting in ssh on LB1, doing ssh to LB2, and executing the "bigpipe fo standby" to put LB2 in Standby mode.
The problem is the same if I force LB1 to Standby... Meaning that I'm getting back access to the GUI console and ssh on LB2, but I loose them on LB1...
I've checked some stuffs, restarted some process (httpd,...).
When I netstat on the problematic device, desired ports (443,...) are in listening mode, so...
Iptables seems also ok...
I'm able to push the configuration on both devices and synch them...
So my question, does someone experienced the same and what's the solution?
At the moment, it's not impacting the applications as the failover is ok. The only problem is that we have to check that the two LBs are not active together...
Thanks,
Phil
