Bug ID 1114861: Local controller etcd instance may become unreachable after a rolling upgrade.

Last Modified: May 29, 2024

Affected Product(s):
F5OS Install/Upgrade, Velos(all modules)

Fixed In:
F5OS-C 1.5.0

Opened: Jun 14, 2022

Severity: 2-Critical


The local etcd instance on a system controller may be unreachable after a rolling upgrade. This can be seen via the output of /etc/etcd/dump_etcd.sh script on the controller.


The local etcd instance will become unreachable. If the local instance on the active controller is unreachable, and the standby controller fails, etcd and the openshift cluster will go offline.


This can happen during a rolling upgrade.



Fix Information

The unreachable etcd instance will be restored once the rolling update is completed.
