HPA Autoscaling Fails with RWO Persistent Volume in New Helm Chart

[mitrevb]

When using the new Helm chart with a ReadWriteOnce (RWO) Persistent Volume and enabling Horizontal Pod Autoscaling (HPA), autoscaling fails due to volume attachment issues.

Issue Details:
• The first pod starts successfully and attaches the RWO volume.
• As HPA scales up, new pods attempt to attach the same RWO volume.
• Since RWO volumes can only be mounted by a single pod at a time, all additional pods get stuck in the ContainerCreating state.

Expected Behavior:
HPA should work correctly, or the chart should handle the RWO volume restriction gracefully.

This is affecting my implementation as well.
