Tons of powershell clustering warnings

[f3rrix]

WARNING: If you are running Windows PowerShell remotely, note that some failover clustering cmdlets do not work remotely. When possible, run the cmdlet locally and specify a remote computer as the target. To run the cmdlet remotely, try using the Credential Security Service Provider (CredSSP). All additional errors or warnings from this cmdlet might be caused by running it remotely.

I'm using 5.46. It looks like this is a failovercluster change, its commands started dumping this warning each time they are called. Since AL calls these commands a lot, the output window has become a deluge of the above warning, swallowing all other output.

Does everyone else get this now too? Is there a known workaround?

Can you share your lab deployment script here, please? I do not see these warnings and would like to understand which section of AL might cause them.

[f3rrix]

Sure. Any lab definition using hyper-v does this, even a trivial one like:

New-LabDefinition -Name GettingStarted -DefaultVirtualizationEngine HyperV Add-LabMachineDefinition -Name FirstServer -OperatingSystem 'Windows Server 2016 Standard' install-lab

Do you run it in a cluster? If not, you can disable those checks with
Set-PSFConfig -Module 'AutomatedLab' -Name DisableClusterCheck -Value $true -PassThru | Register-PSFConfig

We need to check if the VMs are on some other cluster node in case AL is used on a cluster. For a quick fix in this case, you could set the warning action:

$psdefaultparametervalues = @{
'*Cluster*:WarningAction' = 'SilentlyContinue'
}

[f3rrix]

Nope it's not a cluster; Thanks I'll disable those checks!

[f3rrix]

Update: the warning still appears even after DisableClusterCheck. I have not looked at the code to see whether all of the get-cluster commands etc. are actually wrapped in that check. Should be do-able to determine.

More weirdly, setting the $psdefaultparametervalues also doesn't work:

• (Note calling 'new-labdefinition' deletes the value, but you can re-set it after that call)
• Then when I run 'add-labmachinedefinition' and the warning still pops out EVEN THOUGH the value stays set after the command. So maybe something is internally adjusting it or running it in a different context. Next I'll try setting that in my profile in case that helps it to be correct in whatever context it's running.

[nyanhp]

I'll look into it. It originates within New-LabVm. Unfortunately I did not add the check there, instead we check for DoNotAddVmsToCluster :)

So, if you add this as well, you should be fine while I think about doing this properly:

Set-PSFConfig -Module 'AutomatedLab' -Name DisableClusterCheck -Value $true -PassThru | Register-PSFConfig
Set-PSFConfig -Module 'AutomatedLab' -Name DoNotAddVmsToCluster -Value $true -PassThru | Register-PSFConfig

The "problem" is, that you apparently have the Cluster cmdlets available on your machine, hence AutomatedLab still tries to get the cluster, which produces a bunch of warnings:

AutomatedLab/AutomatedLab/AutomatedLabVirtualMachines.psm1

Line 50 in 069b83f

if (-not $doNotAddToCluster -and (Get-Command -Name Get-Cluster -ErrorAction SilentlyContinue) -and (Get-Cluster -ErrorAction SilentlyContinue))

[f3rrix]

I hacked the module files to add:

-WarningAction SilentlyContinue

in each cluster command that was being called, and that was the only thing that could silence it. (They do not honor setting the WarningAction via $psdefaultparameters )

[f3rrix]

In case anyone else wants this, the following commit:

f3rrix@afad43e

is exactly what I changed to mute these warnings. I'm not sure why I started getting these and no one else did, so I don't know whether my changes would be generally useful.

@nyanhp has fixed this in the latest release 5.46.23 built last week. You can get it from GitHub or the PowerShell Gallery:

PS C:\Users\randr> Find-Module AutomatedLab -AllowPrerelease

Version              Name                                Repository           Description

5.46.23-preview      AutomatedLab                        PSGallery            Automated lab environments with ease -...

I guess it is time for a new release.

Cool!
