Description
The Optimize-Volume cmdlet optimizes a volume, performing 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.
