• Please call out in the README that changing persistence.size on an existing deployment will fail to upgrade due to immutable volumeClaimTemplates, and provide explicit remediation steps (e.g., manual PVC handling or setting the value to match existing clusters). This will prevent users from encountering the StatefulSet 'spec: Forbidden' error during upgrade.

Changing the StatefulSet's volumeClaimTemplates size from 128Gi to 64Gi will cause Helm upgrades to fail with 'StatefulSet.apps ... is invalid: spec: Forbidden' because volumeClaimTemplates are immutable. To avoid upgrade failures, keep the existing size (128Gi) or document a migration path (e.g., retain PVC and recreate the StatefulSet, or use storage class expansion where supported) rather than changing this default.

Suggested change

	size: 64Gi
	size: 128Gi

The cleanup now targets only /data/vector/logs, but customConfig still writes to /data/vector/events and /data/vector/metrics. Those files will not be rotated and can fill the PVC over time. Either include events and metrics directories in the cleanup or revert to the previous storage-wide policy.
