Creating a PersistentVolumeClaim (PVC)

Use this information for PersistentVolumeClaim (PVC) configuration settings.

The IBM block storage CSI driver supports using both file system and raw block volume types.

Important: If not defined, the default type is Filesystem. Be sure to define the type as Block if this configuration is preferred.

Note: The examples below create the PVC with a storage size 1 Gb. This can be changed, per customer needs.

Use the sections below for yaml creation of PVCs with file system and raw block volume types. After yaml creation, use the kubectl apply command.

$> kubectl apply -f <filename>.yaml

The persistentvolumeclaim/<filename> created message is emitted.

Creating PVC for volume with file system

Create a PVC demo-pvc-file-system.yaml file with the size of 1 Gb.

Note: volumeMode is an optional field. Filesystem is the default if the value is not added.

Creating PVC for raw block volume

Create a PVC demo-pvc-raw-block yaml file with the size of 1 Gb.

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: demo-pvc-raw-block
spec:
  volumeMode: Block
