Hello Team,

Getting below issues while upgrading and attaching pvc to statefulset component "ingester"

"Error: UPGRADE FAILED: cannot patch "loki-loki-distributed-ingester" with kind StatefulSet: StatefulSet.apps "loki-loki-distributed-ingester" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden && cannot patch "loki-loki-distributed-querier" with kind StatefulSet: StatefulSet.apps "loki-loki-distributed-querier" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden"

Hi,

Delete your ingester's sts by making a backup first and restart your helm deployment
