PSEnsure using Map Expression (Hash Table)

[Jonathan.Engstrom]

Hello,

I am using a PSensure to collect the information. I have a map expression configured on the server variable as to to check for disk labels:
%DiskLabel %(C: OSDisk, D: DataDisk1)

And this runs in a role to collect for each server it is assigned to:
##AH:UseTextMode

## Ensure Disk Label configuration
PSEnsure
(
    Key: Disk Label Check,
    Value: True,
    Collect: >>
        $ServerVariable = $DiskLabel
        $Disks = Get-WmiObject -Class Win32_LogicalDisk -Filter "DriveType=3"
        $ServerVariable.GetEnumerator() |ForEach-Object {  if ( ($Disks.DeviceID).Replace(':','') -contains ("$($_.Key)")) { $y = $disks | Where-Object -Property DeviceID -match $_.Key; $y.VolumeName -eq $($_.Value) }}
    >>,
    Configure: >>
        write-output "The fix is in"
    >>
);

But when it collects, even though the values are both true, it reports as drift. Ideas?

What is the output of your log?

I think this will always report drift, because in all cases your Collect script will return an array of unknown length (number od drives), where as your Value is always a scalar (true).

The output is the following:

ServerCheckout_DiskLabelCheck

Ensure $ServerVariable = $DiskLabel $Disks = Get-WmiObject -Class Win3 using PowerShell

DEBUG: Collecting configuration...

Yes, you can see that the values aren't the same, so there's drift. "True" is not "True, True".

You'll need to change your PS to only return a scalar/Boolean (i.e. "True"), not an array of values.

Since I wanted all of my values in the array to be true to have success in my PSEnsure I thought of different ways I could do this. I settled on counting the items in the array, and using the fact that $true -eq 1 and $false -eq 0 to build a value that should match the count. I added this to the end:

$array.ForEach({if ($) {$val += $}})

$array.Count -eq $val

Thanks for your help!
