Description

The Optimize-Volume cmdlet optimizes a volume, performing such tasks on supported volumes and system SKUs as defragmentation, trim, slab consolidation, and storage tier processing.

If no parameter is specified, then the default operation will be performed per the drive type as follows.

• HDD, Fixed VHD, Storage Space. -Analyze -Defrag.
• Tiered Storage Space. -TierOptimize.
• SSD with TRIM support. -Retrim.
• Storage Space (Thinly provisioned), SAN Virtual Disk (Thinly provisioned), Dynamic VHD, Differencing VHD. -Analyze -SlabConsolidate -Retrim.
• SSD without TRIM support, Removable FAT, Unknown. No operation.

Examples

Example 1: Perform TRIM optimization

PS C:\>Optimize-Volume -DriveLetter H -ReTrim -Verbose

This example optimizes drive H by re-sending Trim requests. This is useful on SSD media, and thinly provisioned storage.

Example 2: Analyze a volume

PS C:\>Optimize-Volume -DriveLetter H -Analyze -Verbose

This example reports only the current optimization state of drive H.

Example 3: Defragment a volume

PS C:\>Optimize-Volume -DriveLetter H -Defrag -Verbose

This example defragments drive H.

Example 4: Perform slab consolidation

PS C:\>Optimize-Volume -DriveLetter H -SlabConsolidate -Verbose

This example performs slab consolidation on the storage space backing volume H.

Example 5: Tier optimize a volume

PS C:\>Optimize-Volume -DriveLetter H -TierOptimize

This example performs tier optimization on the tiered storage space backing volume H.

Parameters

-Analyze

Analyzes the volume specified for fragmentation statistics. Performs analysis only and reports the current optimization state of the volume.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AsJob

ps_cimcommon_asjob

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:	CimSession[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Defrag

Indicates that the cmdlet initiates defragmentation on the specified volume. Defragmentation consolidates fragmented regions of files to improve performance of sequential reads or writes.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DriveLetter

Specifies the drive letter of the volume to optimize.

Type:	Char[]
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-FileSystemLabel

Specifies the file system label of the volume to optimize.

Type:	String[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-InputObject

Accepts a volume object from the pipeline as input.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ObjectId

Specifies the ID of the volume to optimize.

Type:	String[]
Aliases:	Id
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Path

Specifies the path of the volume to optimize.

Type:	String[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ReTrim

Generates TRIM and Unmap hints for all currently unused sectors of the volume, notifying the underlying storage that the sectors are no longer needed and can be purged. This can recover unused capacity on thinly provisioned drives.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SlabConsolidate

Indicates that the cmdlet performs slab consolidation on the storage to optimize slab allocations and to reduce the number of used slabs.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TierOptimize

Indicates that the cmdlet performs tier optimization of the volume, which places file data on the optimal storage tier according to heat or desired placement. This parameter only applies to tiered spaces volumes with more than one storage tier.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Inputs

CimInstance

You can use the pipeline operator to pass a Volume object to the InputObject parameter.

Outputs

This cmdlet does not generate output.
