6.3.7. Create PVCs (Persistent Volume Claims)

Use the following command to create a PVC

kubectl apply -f <volume.yaml>

For example:

kubectl apply -f raid10-volume.yaml

For non-protected volumes, use a YAML such as this:

server:~/AKS_example$ cat raid0-volume.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
 name: block-pvc-r0
spec:
 accessModes:
   - ReadWriteMany
 volumeMode: Block
 resources:
   requests:
     storage: 10Gi
 storageClassName: nvmesh-raid0

The following example is for protected volumes:

server:~/AKS_example$ cat raid1-volume.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
 name: block-pvc
spec:
 accessModes:
   - ReadWriteMany
 volumeMode: Block
 resources:
   requests:
     storage: 10Gi
 storageClassName: nvmesh-raid1

The following example is for protected volumes with higher performance by using more drives in parallel:

server:~/AKS_example$ cat raid10-volume.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
 name: block-pvc-r10
spec:
 accessModes:
   - ReadWriteMany
 volumeMode: Block
 resources:
   requests:
     storage: 10Gi
 storageClassName: nvmesh-raid10

After creating one PVC of each of the examples, verification will show the following:

server:~/AKS_example$ kubectl get pvc
