SimpleScalable deployment mode with filesystem storage?

Hello.
I decided to upgrade to Loki 3.0. and to try deploymentMode: SimpleScalable used to be SingleBinary.
But I can’t install it in any way, I get this error.

Error: UPGRADE FAILED: execution error at (loki/templates/validate.yaml:19:4): Cannot run scalable targets (backend, read, write) or distributed targets without an object storage backend.

If I look at the validation file, there is this condition.

{{- if and $isUsingFilesystem (and (eq $singleBinaryReplicas 0) (or $atLeastOneScalableReplica $atLeastOneDistributedReplica)) }}
{{- fail "Cannot run scalable targets (backend, read, write) or distributed targets without an object storage backend."}}
{{- end }}

Do I understand correctly that SimpleScalable mode with a simple filesystem (pv/pvc) is not possible in K8S?

Thanks.

The error is quite clear. you cannot run simple scalable mode without an object storage backend.

This is exactly what I wanted to hear. Thanks!
