Brainfreeze..... Snapshot used space

[JGPSHNTAP]

Ok, i'm suffering from a brainfreeze today.....

Im looking to find active snapshot used space on volumes and i'm having an absolute brainfreeze....   Will someone kick start my brain for me...

I tried get-nahelp *snapshot* but nothing there

you can get the total snap usage from:

( get-naefficiency vol0).SnapUsage

Perfect.. With all the powershell I do, I never used that cmdlet..  Cool, I will use it.. thanks...

[JGPSHNTAP]

This did the trick..

"{0:N0}" -f( (((get-naefficiency vol1).snapusage).used ) / 1gb)

- a clever and very terse code - but when ran I get 'NO' - how would this provide me with your request [...active snapshot used space on volumes...]?

Peter,

Im not following you on this?   The above code works without issue.. Can you paste what you put and output.. (Take out any company specifics)

JGPShntap -

My bad - I re-ran the script - this time copy&paste -  I got the correct answer - I think my brackets were not spaced correctly

::

"{0:N0}" -f( (((get-naefficiency vol0).snapusage).used ) / 1gb)

There is many ways to skin a cat here.. I did it that way b/c I was using it in an excel spreadsheet.

But if you just want to see output, you can send it to convertto-formattednumber

PS C:\powershell> ((get-naefficiency vol0).snapusage).used  | convertto-formattednumber

55G

Or i wrote a function that i load as a module

Function Convert-togb()
{
Param (
[Parameter(Position=0,Mandatory=$True,ValueFromPipeline=$True)]
#[int]$data
$data
)

Process {
[math]::truncate($data/1gb)
}

}

and I just send it to that

PS C:\powershell> ((get-naefficiency vol0).snapusage).used  | convert-togb
