DESCRIPTION

The New-Volume cmdlet creates a volume with the specified file system. The cmdlet manages the creation of the virtual disk with the specified size and resiliency setting, initializes the disk, creates a partition on it and formats the volume with the specified file system, including Cluster Shared Volumes (CSVs).

EXAMPLES

Example 1: Create a volume on a mirror space

PS C:\> New-Volume -StoragePoolName "CompanyData" -FriendlyName "TestVolume" -Size 10GB -ResiliencySettingName "Mirror" -FileSystem NTFS -AccessPath "M: "-ProvisioningType Fixed

This command creates a new storage space in the CompanyData pool using the Mirror resiliency setting and fixed provisioning, and then formats the volume with the NTFS file system and assigns drive letter M.

Example 2: Create a volume on a new tiered storage space

PS C:\>New-Volume -StoragePoolFriendlyName "CompanyData" -FriendlyName "UserData" -AccessPath "M:" -ResiliencySettingName "Mirror" -ProvisioningType "Fixed" -StorageTiers (Get-StorageTier -FriendlyName "*SSD*"), (Get-StorageTier -FriendlyName "*HDD*") -StorageTierSizes 20GB, 80GB -FileSystem NTFS

This command creates new storage space in the CompanyData pool using the Mirror resiliency setting, fixed provisioning, a 20 GB SSD storage tier, and an 80 GB HDD storage tier, and then formats the volume with the NTFS file system and assigns drive letter M.

-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
Parameter Sets: (All)

Required: False
Position: Named
Default value: None
Accept pipeline input: False

Aliases: 

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

-WriteCacheSize

Specifies the size of the write-back cache. The cmdlet creates the write-back cache of the size that you specify when the cmdlet creates the virtual disk space.

The following describes the behavior of this parameter based on the value that you specify:

  • 1. If you do not specify this parameter, the cmdlet sets the value of the WriteCacheSizeDefault property from the storage pool.
  • 2. The default setting of WriteCacheSizeDefault for a storage pool is Auto, which specifies that Windows Server automatically selects the optimal write-back cache size for your configuration. You can change the value of WriteCacheSizeDefault to a concrete value at any time.
  • 3. The Auto setting for WriteCacheSize operates as follows: ---- a. If any of the following is true, Auto is set to 1 GB: ------ i. The storage pool contains at least N drives with enough capacity and you set the Usage parameter to Journal. N = 1 for simple spaces, N = 2 for two-way mirror and single parity, N = 3 for three-way mirror and dual parity. ------ ii. The storage pool contains at least N drives with enough capacity and the media type of the virtual disk is set to SSD. N = 1 for simple spaces, N = 2 for two-way mirror and single parity, N = 3 for three-way mirror and dual parity. ---- b. Otherwise, Auto is set to 0 (no log) for simple and mirror spaces, and 32 MB for parity spaces.
  • 4. If you specify Auto or 0 (zero) for this parameter and the storage space is not a parity space, the cmdlet verifies that either 3.a.i or 3.a.ii is true. If either 3.a.i or 3.a.ii is not true, you cannot set WriteCacheSize to Auto or 0. ---- a. The objective of these conditions is to help you avoid scenarios in which you force the creation of a write-back cache in situations that result in slower performance.

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

INPUTS

Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_StoragePool

You can use the pipeline operator to pass an MSFT_StoragePool object to the InputObject parameter.

OUTPUTS

Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/Storage/MSFT_Volume

This cmdlet outputs an object that represents the newly created volume.

NOTES

  • To create a volume on a new storage space with enclosure-awareness enabled (providing resiliency for an entire JBOD enclosure failure), use the Set-StoragePool cmdlet with the -EnclosureAwareDefault $true parameter to set the storage pool to create storage spaces with enclosure awareness enabled by default.
