Powercli Commands to list SnapShot size on a Datastore?

[gedamagic]

I am seeking a PowerCLI command to list SnapShots size with a Datastore on the storage level.  I could not find the information in GUI.

Thank You!

You could do something like this

$dsName = 'datastore1'

$ds = Get-Datastore -Name $dsName

$snaps = $ds | Get-VM | Get-Snapshot

$ds | Select Name,@{N='SnapshotSizeGB';E={

   [math]::Round(($snaps | Measure-Object -Property SizeGB -sum).Sum,1)}}

LucD,

I am looking for Snapshots for Datastore on NFS storage level, not for VM's. 

Thanks for replying.

[LucD]

Not sure I get what you mean.
Can you show a screenshot? Or some more details?

.snapshot

this is the folder in vSphere.

Commands you showed me is for snapshots accumulated by VM's.

The snapshots I am talking about is taken by the storage, not by VM's or vShpere.

Ok, got it.

Try something like this

$datastoreName = 'MyDS'

$ds = Get-Datastore -Name $datastoreName

New-PSDrive -Location $ds -Name DS -PSProvider VimDatastore -Root '\' | Out-Null

$size = Get-ChildItem -Path "DS:\.snapshot" -Recurse | Measure-Object -Property Length -Sum | select -ExpandProperty Sum

Remove-PSDrive -Name DS -Confirm:$false

Write-Host "Folder .snapshot holds $([math]::Round($size/1GB,1)) GB"

[gedamagic]

Your script is hanging on the line with Recursive...

Any idea why?

Thanks!

The datastore provider is not extremely fast.

I suspect it just might be running for a very long time.

You could test with a datastore that has less content.

After extremely long time, it finally broken.  The Snapshots size is not that large, only 10 ones.

[LucD]

Do you mean 'completed' or 'ended with an error' with 'broke'?

It's not as much the size of the files in that folder, more the number of files and how deep the folders are nested, that determines how long it will run.

An alternative, and faster method, would be to connect via SSH to the ESXi nodes, and do a 'du' from there.

But it require to enable SSH and have access to an account that can logon on the ESXi node.
