F5 Load Balancer Only Recognizes 2 of 5 Worker Nodes as Active in OKD Cluster #2043

@vrutkovs kindly your support After installing the OKD cluster with the following configuration:

OKD version is: 4.15 stable fedora core os version : fedora-coreos-40.20240728.3.0-metal.x86_64.raw.xz installation type is: any platform platform in VM's in VMware

3 master nodes 5 worker nodes 2 load balancers (LB) in F5, handling: Ports 6443 and 22623 Ports 443 and 80 All worker nodes are ready and functioning properly within the cluster. However, the F5 load balancer only recognizes 2 worker nodes as active, while the remaining 3 are marked as inactive.

When I attempt to telnet to port 443:

It works on the active nodes as seen by the F5. It does not work on the inactive nodes, neither from the VMs' IPs nor from within the VMs themselves (the 443 port is not responding). How can I resolve this issue to ensure that all worker nodes are active in F5 and capable of handling incoming application requests?

Hi,

The OKD Working Group is transitioning OKD to an SCOS base and can only provide minimal guidance on versions <= 4.15. Please see these documents...

https://okd.io/blog/2024/06/01/okd-future-statement https://okd.io/blog/2024/07/30/okd-pre-release-testing

We will be providing documentation on upgrading clusters from 4.15 FCOS to 4.16 SCOS when a stable release is available.

Many thanks,

Jaime
