View Persistent Volume Details
This section explains how to view details of Persistent Volumes in the cluster.
Prerequisites
You should join a cluster and have the Persistent Volume Claim Viewing permission within the cluster. For more information, refer to "Cluster Members" and "Cluster Roles".
Steps
-
Log in to the KubeSphere web console with a user who has the Persistent Volume Claim Viewing permission, and access your cluster.
-
Click Storage > Persistent Volume Claims in the left navigation pane.
-
On the Persistent Volume Claims page, click Persistent Volume to open the list of Persistent Volumes. Then, click the name of a Persistent Volume to open its details page.
-
On the left side of the Persistent Volume details page, in the Attributes section, view the resource attributes of the Persistent Volume.
Parameter Description Status

-
Available: The Persistent Volume is not bound to any Persistent Volume claim. The KubeSphere web console currently does not support the direct creation of Persistent Volumes. If you create Persistent Volumes directly using backend command-line tools, the Persistent Volumes will have a status of Available. For more information, refer to the Kubernetes Documentation.
