Volume TotalSize

sjallabais — Thu, 05 Jun 2025 06:45:25 GMT

How can I get the total size of a volume, regardless of the snap reserve setting?

(do I really need to calculate my self??)

In a new empty 100g volume with the default 20% snap reserve, SystemManager reports 100g TotalSpace and 80g AvailableSpace,

while the toolkit returns this:

PS C:\> Get-NaVol testvol |fl

Hi Sjallabais!

You can use the SnapshotBlockReserved and SnapshotPercentReserved members returned by Get-NaVol to calculate the size of the volume including the snap reserve, or you can use the Get-NaSnapshotReserve cmdlet like this:

PS C:\> (Get-NaVol testvol).TotalSize + (Get-NaSnapshotReserve testvol).Size

21474836480

Hope that helps!

And Get-NaVolSize works pretty good too.

PS C:\> get-navolsize testvol

VolumeSize

Thanks!

(although for easier coding, it would have been nice that i was available directly from the Get-NaVol cmdlet)
