Alternative for "df -hs" in powershell cmdlet



I want to find out how much data is saved through deduplication with volumes on a cmode cluster, and so far I haven't found a cmdlet that'll display properties that'd be displayed if I typed "df -hs" on a 7-mode filer.  get-ncvol can show me whether a volume is deduped, but I don't see any other property that I can use to calculate the amount saved.  I don't see anything that'd allow me to do that in get-ncvol either.  Is there a way to get this info?

I'd like to see this baked into a native cmdlet too.  In the meantime, you can get that data using this:

Invoke-Nassh "df -hs"

You may be able to find the information you are looking for in the volume sis attributes returned by Get-NcVol:
