Verify Node Labels For Storage Classes

Overview

Each node serving persistent storage should have akash.network/storageclasses label set. These labels are automatically applied and this section we will verify proper labeling.

NOTE - currently the Helm Charts for persistent storage support only a single storageclass per cluster. All nodes in the cluster should be marked as beta2 - as an example - and cannot have a mix of beta2 and beta3 nodes.

Node Label Verification

Verification Template

  • Replace <node-name> with actual node name as gathered via kubectl get nodes
kubectl describe node <node-name> | grep -A10 Labels

Example/Expected Output

root@node1:~# kubectl describe node node2 | grep -A10 Labels
Labels:             akash.network=true
                    akash.network/capabilities.storage.class.beta2=1
                    akash.network/capabilities.storage.class.default=1
                    allow-nvdp=true
                    beta.kubernetes.io/arch=amd64
                    beta.kubernetes.io/os=linux
                    kubernetes.io/arch=amd64
                    kubernetes.io/hostname=node2
