      SECTION

      Loki deployment sizing

      DESCRIPTION

      The Total disk requests for 1x.extra-small are 430Gi, the same that for 1x.small as per Loki deployment sizing documentation. But, for the Loki size 1x.extra-small the correct value for Total disk requests  is 220G:

      $ oc get pvc
      NAME                                   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE

      storage-logging-loki-ingester-0        Bound    pvc-73f62234-bbe5-4b53-a542-2bcf23e684d7   10Gi       RWO            gp3-csi        27s
      wal-logging-loki-ingester-0            Bound    pvc-67c95bc3-8032-4cba-b6b6-84934144acde   150Gi      RWO            gp3-csi        27s 

      Then, also the Total disk requests if using the ruler value is incorrect, currently it's 750G and it should be: 540G (220G of Total disk requests + 320 of the Loki Ruler)

       

      ADDITIONAL NOTES

      It should be useful to indicate that the Total disk requests and the Total disk requests if using the ruler are the GB requested to the Block STorage, temporary storage, and not related to the object storage.
