Resizes a virtual hard disk.
Resize-VHD [-Path] <String> [-SizeBytes] <UInt64> [-AsJob] [-ComputerName <String>] [-Passthru] [-Confirm] [-WhatIf] [<CommonParameters>]
Resize-VHD [-Path] <String> [-AsJob] [-ComputerName <String>] [-Passthru] -ToMinimumSize [-Confirm] [-WhatIf] [<CommonParameters>]
The Resize-VHD cmdlet resizes a virtual hard disk. This cmdlet lets you shrink or expand the size of a virtual hard disk, but the shrink operation is allowed only on VHDX
virtual hard disks. The shrink operation fails if it would shrink the virtual disk to less than its minimum size (available through the VHDX object’s MinimumSize property).
Resize-VHD is an offline operation; the virtual hard disk must not be attached when the operation is initiated.
