Currently,

the storageclass for ingestor is currently hardcoded to do-block-storage:
https://github.com/parseablehq/parseable/blob/main/helm/templates/ingestor-statefulset.yaml#L69-L77

[...] volumeClaimTemplates: - metadata: name: stage-volume spec: accessModes: [ "ReadWriteOnce" ] storageClassName: "do-block-storage" resources: requests: storage: 10Gi 

This should be changed, so you can also use the ingestor on other cloudproviders than digitalocean.

possible solution would be to use the same code as for the data or stage pvc:
