Hello!

We are testing the latest module releases (framework 1.10.0, plugins 1.10.0, hyperv 1.2.0) and we found the following behaviour on two machines:

The error is: Icinga Exception: Exception calling "Add" with "x" argument(s): "Item has already been added.
and the following checks are affected on both machines:

Invoke-IcingaDiskHealth
InvokeICingaCheckHyperVOvercommitment
InvokeICingaCheckHyperVSnapshot
InvokeICingaCheckHyperVVMHealth

Expected Behavior

The checks should work without errors.

Current Behavior

PLease see above.

Steps to Reproduce (for bugs)

unknown

Your Environment

OS: Microsoft Windows Server 2019 Datacenter v.10.0.17763
-all have the same patchlevel
-all have vms (online)
-there are no cluster-events indicating an error

Thats an issue related to the Plugins provider for the disk metadata. It seems for some reasons the same id's are added

[K0nne]

Can I somehow help you with the debugging?

[LordHepipud]

Can you please execute the following commands on the machine causing the problem and share the result? I do not understand on why there are two disks present with the same id

Get-CimInstance -ClassName Win32_DiskDrive | Select-Object DeviceId, Caption, SerialNumber;

Get-CimInstance -ClassName MSFT_PhysicalDisk -Namespace 'root\Microsoft\Windows\Storage' | Select-Object
 SerialNumber, DeviceId, Model;

[K0nne]

You won't believe it. I can't reproduce the issue anymore. Its gone on all affected machines, als if Microsoft has patched it away ^^
