9.5 Update 4a - Powershell - Possible race condition?

[SvenP]

Before upgrading to version 9.5 update 4a, something like

Code: Select all

$NewJob = Add-VBRViBackupJob -Name "$JobName" -Description "$Description" -Entity $Entity -BackupRepository $Repository
Set-VBRJobAdvancedViOptions -Job $NewJob -VMToolsQuiesce $True

worked without any problems in a Cmdlet (the variables are set, of course).

After the upgrade the VMToolsQuiesce option is not set. If I enter the second code line manually some time (here is the possible race condition) afterwards the option will be set.
Same goes for

Code: Select all

Set-VBRJobAdvancedViOptions -Job $NewJob -SetResultsToVmAttribute $True -VmAttributeName "veeam"| Out-Null

Also in the variations

Code: Select all

# first query the new created job
Get-VBRJob -Name "$JOBName"|Set-VBRJobAdvancedViOptions -SetResultsToVmAttribute $True -VmAttributeName "veeam" | Out-Null
#or
Get-VBRJob -Name "$JOBName"|Set-VBRJobAdvancedViOptions -SetResultsToVmAttribute $True -VmAttributeName "veeam"

No errors are printed nor exceptions thrown. Inserting "sleep" didn't help either. Has anyone else experienced the same problem? Any ideas for a remedy?

Hello,
I tested your code and it works for me. The quiesce option was set correctly.

Code: Select all

Add-PSSnapin VeeamPSSnapin
$Entity = Find-VBRViEntity -Name HK-Nano
$NewJob = Add-VBRViBackupJob -Name "BJ-Quiesce" -Description "Description" -Entity $Entity  -BackupRepository VBR-01-ReFS64k-Repo1
Set-VBRJobAdvancedViOptions -Job $NewJob -VMToolsQuiesce $true

As it seems to be a specific case, I suggest opening a support case. Please post the case number for reference.

Thanks,
Hannes

Thank you! I will do so after the holidays when the office is manned again.

I've also confirmed your script that sets attributes, so, it indeed seems to be environment specific problem. Thanks!

So, finally opened Case # 03582291 a few minutes ago, let's wait and see.

Hi there, it was a race condition in my own script. Short version:

Code: Select all

$NewJob = Add-VBRViBackupJob -Name "$JobName" -Description "$Description" -Entity $Entity -BackupRepository $Repository
$JobOptions = Get-VBRJobOptions -Job $NewJob
Set-VBRJobAdvancedViOptions -Job $NewJob -VmAttributeName "veeam" -SetResultsToVmAttribute $True
Set-VBRJobAdvancedViOptions -Job $NewJob -VMToolsQuiesce $True
Set-VBRJobOptions -Job $NewJob -Options $JobOptions

$JobOptions contains the state before setting VMToolsQuiesce for example. When writing with Set-VBRJobOptions the old state overwrites the option. It was hard to track down because those things did not happen in 4 lines of code; they were some screens apart. Plus: it worked with older versions of Veeam (I've checked the Git history of the script)
