StackLight known issues¶
This section lists the StackLight known issues with workarounds for the Mirantis OpenStack for Kubernetes release 22.4.
[28372] False-positive liveness probe failures for ‘fluentd-notifications’¶
If a cluster does not currently have any ongoing operations that comprise
OpenStack notifications, the fluentd containers in the
fluentd-notifications Pods are frequently restarted due to false-positive
failures of liveness probe and trigger alerts.
Ignore such failures and alerts if the Pods are in the Running state.
To verify the fluentd-notifications Pods:
kubectl get po -n stacklight -l app=fluentd
Example of system response:
fluentd-notifications-64fdc5f5cd-pgmjp 1/1 Running 9 4h51m
fluentd-notifications-64fdc5f5cd-xjfrs 1/1 Running 9 4h51m
