Deploy using helm without zone-aware replication and any PVC

[libormezl]

Hi, I am quite new to the LGTM stack. I have successfully deployed Grafana with Tempo to our AKS cluster, but I am having some issues with Mimir.

I am deploying using Helm. My goal is to deploy Mimir in microservice mode without zone-aware replication (we don't need it) and without using any PVCs, as I want to use Azure Storage as the storage solution.

I have disabled zoneAwareReplication and also set persistentVolume.enabled=false for all services in my Helm configuration. I have set up Azure Storage (it seems to be working).

However, I am encountering two issues with the configuration:

• When I query from Grafana, I get too many unhealthy instances in the ring.
• When I push data from the OTEL Collector, the collector reports responded with HTTP Status Code 503, Message=send data to ingesters: at least 1 live replica required, could only find 0

Is it possible to achieve my goal, or is it necessary to have PVCs?

PVCs are required for ingesters. PVCs are not required, but strongly recommended for store-gateways, to avoid slow startup. PVC is also recommended for compactors, to being able to guarantee requested iops.
