vSAN -- "vsan-healthcheck-disposable*" VMs created across Infrastructure and are not automatically removed after vSAN Test

Products

• VMware vSAN
• VMware vSAN 7.x
• VMware vSAN 8.x

Issue/Introduction

VMs with their names containing "vsan-healthcheck-disposable*" are being automatically created & deleted by the System,

when manually triggering the "VM Creation Test"

which can be found in the vSphere Web Client --> vSAN Cluster --> Monitor --> vSAN --> VM Creation Test

 

 

 

While this Test was not manually triggered, VMs with their names containing "vsan-healthcheck-disposable*" are being found in the vSphere Web Client,

while not being automatically deleted by the System.

 

 

 

 

 

 

Environment

vSAN 7.x

vSAN 8.x

 

 

Cause

The creation of these "vsan-healthcheck-disposable*" VMs was triggered by a custom script, Monitoring Tool and/or 3rd Party Product,

using a timeout value which is too small to complete the VM creation task. 

 

Result:

Despite the VM being created, the task internally timed out.

As a result the System is unable to follow up on the task, resulting in the fact that the "vsan-healthcheck-disposable*" VM is not being deleted by the System.

 

Resolution

A.) The "vsan-healthcheck-disposable*" VMs can be deleted manually without any risk by right-clicking the VM --> Delete from Disk

 

B.) The custom script, Monitoring Tool and/or 3rd Party Product which triggers the automatic generation of "vsan-healthcheck-disposable*" VMs

needs to be adjusted by increasing the programmed Timeout value to 2 minutes.

 

In the case that a custom PowerShell script is used, based on official PowerCLI module and command : "Get-VsanView"

Please change the Timeout X mentioned in this line:

$result = $vchs.VsanQueryVcClusterHealthSummary($VsanCluster.Id, X, $null, $true, $null, $fromCache, 

 

to this:

$result = $vchs.VsanQueryVcClusterHealthSummary($VsanCluster.Id, 120, $null, $true, $null, $fromCache,
