AutoSize

JSHACHER11 — Thu, 05 Jun 2025 05:39:10 GMT

Hi guys,

I would like to get the values of Autosize (maximum and increments) for all the volumes in the filer

I've tried 'Get-NaVol | Get-NaVolAutosize' but it gives no names of the volumes

any ideas?

Cheers

You're looking for something like this

$autosize = get-navolautosize $name -ea "silentlycontinue"

$unit = 1gb

If ($autosize.isEnabled) {

[System.Math]::Floor($autosize.maximumsize/$unit)

[System.Math]::Floor($autosize.incrementsize/$unit)

}

You can start with that in your loop, I use that for an excel output so it's a little different, but those are the properties you need

So in your case

$vols = Get-navol

$vols | % {

$volume = $_

$autosize = get-navolautosize $name -ea "silentlycontinue"

$unit = 1gb

If ($autosize.isEnabled) {

$max = [System.Math]::Floor($autosize.maximumsize/$unit)

$inc = [System.Math]::Floor($autosize.incrementsize/$unit)

write-host "Autosize: enabled " & "maximum size: " $max & "increment size: " $inc

}

Give that a shot, I didn't test it

I've changed it to this:

===================

$vols = Get-navol

$vols | % {

$volume = $_

$autosize = get-navolautosize $name -ea "silentlycontinue"

$unit = 1gb

If ($autosize.isEnabled) {

$max = [System.Math]::Floor($autosize.maximumsize/$unit)

$inc = [System.Math]::Floor($autosize.incrementsize/$unit)}

write-host "Autosize: enabled "

write-host "maximum size: " $max

write-host "increment size: " $inc

===================

but now I am getting this:

Get-NaVolAutosize : Cannot bind argument to parameter 'Name' because it is null.

At C:\autosize.ps1:4 char:30

change $name to $volume

But we should do this the right way with custom objects

$global=@()

$vols = Get-navol

$vols | % {

$volume = $_

$autosize = get-navolautosize $volume -ea "silentlycontinue"

$unit = 1gb

If ($autosize.isEnabled) {

$customobject = new-object psobject

add-member -inputobject $customobject -membertype noteproperty -name Volume -value $volume

add-member -inputobject $customobject -membertype noteproperty -name Autosize -value "enabled"

add-member -inputobject $customobject -membertype noteproperty -name Max -value [System.Math]::Floor($autosize.maximumsize/$unit)

add-member -inputobject $customobject -membertype noteproperty -name increment -value [System.Math]::Floor($autosize.incrementsize/$unit)}

$global += $customobject

}

$global | ft -autosize

###

Try that

Ah, when you write things quick in notepad this happens... Ok, give this a whilr

$global=@()
[Int64]$Unit=1GB

$vols = Get-navol

$vols | % {

$volume = $_

$autosize = get-navolautosize $volume -ea "silentlycontinue"

If ($autosize.isEnabled) {

$customobject = new-object psobject
     add-member -inputobject $customobject -membertype noteproperty -name Volume -value $volume
     add-member -inputobject $customobject -membertype noteproperty -name Autosize -value "enabled"
     add-member -inputobject $customobject -membertype noteproperty -name Max -value ([System.Math]::Floor($autosize.maximumsize/$unit))
     add-member -inputobject $customobject -membertype noteproperty -name increment -value ([System.Math]::Floor($autosize.incrementsize/$unit))

$global += $customobject

}

}
$global | ft -autosize

and then you can dump it to excel

$global | export-csv c:\temp\autosize.csv -notypeinformation

....like a charm!!

thank you

now you just need to explain the 'Floor' command please

Re: AutoSize

JGPSHNTAP — Mon, 31 Mar 2014 18:05:33 GMT

Floor is just round down to next whole number.. You can play with the formatting, but you should be more interested in the custom objects. You can export and import them.. Much easier for scripting

Re: AutoSize

JSHACHER11 — Mon, 31 Mar 2014 18:17:03 GMT

OK, you have my attention

so custom objects are basically properties that we have added to the 'get-navolautosize' cmdlet - what you would normally see with the get-member command, correct?

Re: AutoSize

JSHACHER11 — Mon, 31 Mar 2014 18:22:42 GMT

is it possible to get a table of the max autosize and the volume size (and volume name) - something like this:

name max_autosize vol_size

-------- ----------------- ----------

vol0 124GB 104GB

vol5 640GB 421GB

Re: AutoSize

JGPSHNTAP — Mon, 31 Mar 2014 18:33:06 GMT

Yeah - that's easy

$global=@()
[Int64]$Unit=1GB

$vols = Get-navol

$vols | % {

$volume = $_
$size = ([System.Math]::Floor($_.totalsize/$unit))
$autosize = get-navolautosize $volume -ea "silentlycontinue"

If ($autosize.isEnabled) {

$customobject = new-object psobject
     add-member -inputobject $customobject -membertype noteproperty -name Volume -value $volume
add-member -inputobject $customobject -membertype noteproperty -name size -value $size
     add-member -inputobject $customobject -membertype noteproperty -name Autosize -value "enabled"
     add-member -inputobject $customobject -membertype noteproperty -name Max -value ([System.Math]::Floor($autosize.maximumsize/$unit))
     add-member -inputobject $customobject -membertype noteproperty -name increment -value ([System.Math]::Floor($autosize.incrementsize/$unit))

$global += $customobject

}

}
$global | ft -autosize

Ok - enjoy, I need to get back to work.. if you want total volsize, use that full cmdlet. As for objects, you need to read up on them, they are pretty powerful
