Get-NaSIS and ChangelogUsedPercent

DENISMELONI — Thu, 05 Jun 2025 06:10:29 GMT

Hi, I'm trying to develop a Powershell script and I need to highlight some informations like the "ChangelogUsedPercent" value for deduplicated volumes.

With "sis status -l" in SSH, it's OK, but with Powershell KO (see below).

Is there another way (that works) to get this information in Powershell?

Thanks.

Hi Denis,

Could you try the below command and see if it works

Invoke-NaSsh "sis status -l /vol/j_rec_507"

Great !

But how to put it in a variable, I've tryed :

# $vol=Invoke-NaSsh "sis status -l /vol/j_rec_507"

# $vol."Change Usage" => nothing

# $vol

Path: /vol/j_rec_507

State: Enabled

It's not very pretty, but it works

# recupération du Changelog Used

$vol=Invoke-NaSsh "sis status -l" $volume.path ###volume name

$SearchStart="Changelog Usage: " ###not included in result

$SearchEnd="%" ###not included in result

$vol -match "(?s)$SearchStart(?<content>.*)$SearchEnd"

$result=$matches['content']

$CHANGELOG = [int]$result

So, $CHANGELOG = 3
