Cmdlet: Invoke-NaHostVolumeSpaceReclaim
NAME
Invoke-NaHostVolumeSpaceReclaim
SYNOPSIS
Reclaim free space on a Windows volume that is hosted on a Data ONTAP LUN.
SYNTAX
Invoke-NaHostVolumeSpaceReclaim [[-Path] <String>] [<CommonParameters>]
Invoke-NaHostVolumeSpaceReclaim [-VdsId] <Guid> [<CommonParameters>]
DESCRIPTION
Reclaim free space on a Windows volume that is hosted on a Data ONTAP LUN.
This cmdlet examines the NTFS file system on a Windows volume, locates all f
ree space, and deallocates the corresponding blocks on the Data ONTAP storag
e controller. No difference is apparent from Windows' perspective, but all
space not consumed by files on the volume is freed on the storage controller
.
Cluster-shared volumes (CSVs) are supported, but this cmdlet uses a differen
t reclamation algorithm due to CSV limitations. A CSV may appear to become
up to 98% full during the reclamation process, but this should not pose a pr
oblem even for LUNs that are not space-reserved. There is no requirement fo
r the CSV to be in redirected or maintenance mode to use this cmdlet.
This cmdlet may be run while the Windows volume is online and undergoing act
ive I/O. Administrator privileges are required to use this cmdlet.
