Data Volume

The Data Volume page allows you to manage persistent storage volumes (DataVolumes) used by Virtual Machines in the OtterScale cluster. DataVolumes provide a way to automate the importing, cloning, and uploading of data into Persistent Volume Claims (PVCs).

Introduction

The Data Volume page displays a list of configured DataVolumes. The table includes the following information:

Column	Description
Name	The name of the DataVolume.
Namespace	The Kubernetes namespace where the DataVolume resides.
Phase	The current status of the DataVolume (e.g., Succeeded, ImportInProgress).
Source	The source of the data (e.g., HTTP URL, Blank Image, PVC). Hovering over the badge reveals detailed source information.
Progress	The progress of the data import or clone operation.
Size	The capacity of the volume.

Manage Data Volumes

You can create new DataVolumes or manage existing ones using the Actions menu.
