Reclaiming space on the storage system

Although NTFS tracks the available space on a LUN when files are deleted or modified, it does not report the new information to the storage system. You can run the space reclamation PowerShell cmdlet on the Plug-in for Windows host to ensure that newly freed blocks are marked as available in storage.

Before you begin

If you are running the cmdlet on a remote plug-in host, you must have run the SnapCenter Open-SMConnection cmdlet to open a connection to the SnapCenter Server.

About this task


  1. From the application server PowerShell command prompt, enter the following command: Invoke-SdHostVolumeSpaceReclaim -Path drive_path
    drive_path is the drive path mapped to the LUN.
