Powercli to set DataStore Reclaim Rate

[taskino]

Hello,

Is there a way to set datastore space reclamation rate via PowerCli? I looked number of examples but they all mention about setting via esxcli.  I am looking to set the space reclamation rate from 100 MB/s to 400 MB/s? for number of datastores.

Thank you

You can use all esxcli commands through the Get-EsxCli cmdlet.

Would be great to have some more of that . 

PowerCLI and Datastore ( Reclamation ) , there is not to much content from "Mister Google" and "Mister ChatGPT" is not currently answering  

Mayb @LucD  has a Link he can Post . 

What would be the Synthax to use something like 

esxcli storage vmfs reclaim config set --volume-label datastore_name --reclaim-method fixed -b 100

with PowerCLI ?

You mean like this?

If that would help yes , but I run into error like the other User in the Thread. 

So thanks for the Answer, but It would be nice to pole all Datastores 

Like that ( from someone else, which provide Infos to the Datastores ) 


$Datastores = Get-Datastore
foreach($DS in $Datastores)
{
$DSInfo = $DS.ExtensionData.Info

if($DSInfo -is [VMware.Vim.VmfsDatastoreInfo] -and $DSInfo.Vmfs.MajorVersion -eq 6)
{$DSInfo.Vmfs | select Name, BlockSizeMb,Version, UnmapPriority, UnmapGranularity, Uuid, Extent}

else {
$prop = [ordered]@{Name = $DSInfo.vmfs.Name
BlockSizeMb = $DSInfo.Vmfs.BlockSizeMb
Version = $dsinfo.vmfs.Version
UnmanPriority = "VMFS Version is below 6"
UnmapGranularity = "VMFS version is below 6"
}
New-Object -TypeName psobject -Property $prop | ft -AutoSize
}
}

And then have the ability to change Unmap Priority in a Bulk.

Not sure I understand what you are trying to do.
That script just lists the datastores, where does the unmap come into play?
And what do you mean by "change Unmap Priority in a Bulk"

[mviel]

"change Unmap Priority in a bulk"  sorry , maybe that is wrong english . 

I try identify all those Datastores which have a UnmapPriority "none" and change the UnmapPriority then to "low" . 

If the UnmapPriority is "none" there will be no Space Reclamation going on , if it is "low" Reclamation rate is around 100 MB/s

Something along these lines

Get-Datastore -PipelineVariable ds |
Where{$ds.Type -eq 'VMFS'} |
ForEach-Object -Process {
   $obj = [ordered]@{
      Name = $ds.Name
      BlockSizeMb = $ds.ExtensionData.Info.Vmfs.BlockSizeMb
      Version = $ds.ExtensionData.Info.Version
      UnmanPriority = ''
      UnmapGranularity = ''
      Uuid = $ds.ExtensionData.Info.Uuid
   }
   if (([version]$ds[0].FileSystemVersion).Major -lt 6) {
      $obj.UnmapPriority = "VMFS Version is below 6"
      $obj.UnmapGranularity = "VMFS version is below 6"
   }
   else{
      $obj.UnmapPriority = $ds.ExtensionData.Info.Vmfs.UnmanPriority
      $obj.UnmapGranularity = $ds.ExtensionData.Info.Vmfs.UnmapGranularity

      if ($ds.ExtensionData.Info.Vmfs.UnmapPriority -eq 'none'){
         $esx = Get-VMHost | Get-Random -Count 1
         $esxcli = Get-EsxCli -VMHost $esx -V2
         $arguments = $esxcli.storage.vmfs.reclaim.config.set.CreateArgs()
         $arguments.volumelabel = $ds.Name
         $arguments.reclaimmethod = 'fixed'
         $arguments.reclaimpriority = 'low'
         $arguments.reclaimbandwidth = 100
         $esxcli.storage.vmfs.reclaim.config.set.Invoke($arguments)
      }
   }
}
