= Adding a storage class
|
|
|
|
You can add a storage class to an {product-title} cluster. A storage class describes a class of storage in the cluster and how the cluster dynamically provisions the persistent volumes (PVs) when the user specifies the storage class. A storage class describes the type of device classes, the quality-of-service level, the filesystem type, and other details.

.Procedure
|
|
|
|
. Create a YAML file:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: storage.k8s.io/v1
|
|
kind: StorageClass
|
|
metadata:
|
|
name: lvm-storageclass
|
|
parameters:
|
|
csi.storage.k8s.io/fstype: ext4
|
|
topolvm.io/device-class: vg1
|
|
provisioner: topolvm.io
|
|
reclaimPolicy: Delete
|
|
allowVolumeExpansion: true
|
|
volumeBindingMode: WaitForFirstConsumer
|
|
----
|
|
+
|
|
Save the file by using a name similar to the storage class name. For example, `lvm-storageclass.yaml`.
|
|
|
|
. Apply the YAML file by using the `oc` command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc apply -f <file_name> <1>
|
|
----
|
|
<1> Replace `<file_name>` with the name of the YAML file. For example, `lvm-storageclass.yaml`.
|
|
+
|
|
The cluster will create the storage class.
|
|
|
|
. Verify that the cluster created the storage class by using the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get storageclass <name> <1>
|
|
----
|
|
<1> Replace `<name>` with the name of the storage class. For example, `lvm-storageclass`.
|
|
+
|
|
