VMware Communities: Message List - How to list delta files in all datastores

Re: How to list delta files in all datastores

That should normally be in the vifs.pl command but I'm afraid it doesn't allow masking nor recursive folder listings.

Do you know how to get from command line? RCLI.

I cannot find it.

Thank you

@c_shanklin : your workaround works for me (i got the "You are not currently connected..." case too)

Thanks !

Sure, something I had lying around in my goodies chest

function Get-DatastoreDir ($DSName){

  $dsImpl = Get-Datastore -Name $DSName
  $ds = Get-Datastore -Name $DSName | Get-View
  $dsBrowser = Get-View -Id $ds.Browser

  $datastorepath = "[http://" + $ds.Summary.Name + "|http://" + $ds.Summary.Name + "]"
  
  $searchspec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec
  $searchSpec.matchpattern = "*"
  $searchSpec.details = New-Object VMware.Vim.FileQueryFlags
  $searchSpec.details.fileSize = $true
  $searchSpec.details.fileType = $true
  $searchSpec.details.modification = $true
 
  $taskMoRef = $dsBrowser.SearchDatastoreSubFolders_Task($datastorePath, $searchSpec) 
  $task = Get-View $taskMoRef 
  while ($task.Info.State -eq "running"){$task = Get-View $taskMoRef}

  $report = @() 
  foreach ($result in $task.info.Result){
    foreach($file in $result.File){
      if($file.GetType().Name -ne "FolderFileInfo"){
	    $row = "" | Select Filename, Folder, Filesize, Modification
        $row.Filename = $file.Path
	    $row.Folder = $result.FolderPath
	    $row.Filesize = $file.FileSize
	    $row.Modification = $file.Modification
	    $report += $row
	  }
    }
  }
  $report
}

Get-DatastoreDir <datastore-name> | Where-Object {$_.Filename -match "flat"}

If you want to do this for all your datastores you could change the last line to

Get-Datastore | %{Get-DatastoreDir $_.Name} | Where-Object {$_.Filename -match "flat"}

Des anyone have a method to search all datastores for "delta" files, without using the VI Toolkit Community Extensions?

Re: How to list delta files in all datastores

kastek — Tue, 14 Oct 2008 18:43:07 GMT

Still not working...same error

Re: How to list delta files in all datastores

c_shanklin — Tue, 14 Oct 2008 18:25:25 GMT

There is a scoping problem with the $defaultVIServer variable.

This is a workaround: in your script change:

Connect-VIServer -Server 192.168.xxx.xxx -User xxx -Password xxx

$server = Connect-VIServer -Server 192.168.xxx.xxx -User xxx -Password xxx
$global:defaultVIServer = $server

It seems there is something peculiar about script cmdlets that makes them run in a different context from other cmdlets. The way we populate and use $defaultVIServer is probably not helping.

Yes I do see the "Name Port User" in the output

Re: How to list delta files in all datastores

kastek — Tue, 14 Oct 2008 18:02:06 GMT

Yes I do get output...and just to clarify...when I issue the commands one at a time inside powershell it works fine...just doesn't work via the script?

Re: How to list delta files in all datastores

LucD — Tue, 14 Oct 2008 17:58:51 GMT

Add-Module is a cmdlet from PowerShell v2, and PowerShell 2 CTP2 is required for the VITK Community Extensions.
So that should be ok.

And I can't see anything wrong in the script.
Are you sure the Connect-VIServer is working ?
Do you see the "Name Port User" message in the output ?

Re: How to list delta files in all datastores

c_shanklin — Tue, 14 Oct 2008 17:57:38 GMT

The problem may be that the connection is not actually succeeding.

Can you replace line 6 with just "get-datastore" and see if you get any output?

Re: How to list delta files in all datastores

kastek — Tue, 14 Oct 2008 17:52:20 GMT

Line 4...you mean the one that adds the viToolkitExtensions.psm1?

If I don't have that the "get-tkedatastorefile" command is not recognized.

Re: How to list delta files in all datastores

Skark166 — Tue, 14 Oct 2008 17:42:09 GMT

I think you'd be ok if you ditched line 4.

Script attached...

Re: How to list delta files in all datastores

LucD — Tue, 14 Oct 2008 17:35:29 GMT

To further analyse what exactly goes wrong it would perhaps be useful if you posted the script.

Re: How to list delta files in all datastores

kastek — Tue, 14 Oct 2008 17:30:54 GMT

Thanks LucD...but I do call the "Connect-VIServer" command already?

Re: How to list delta files in all datastores

LucD — Tue, 14 Oct 2008 17:16:08 GMT

That loads the VITK snapin and defines some aliases and functions (in Initialize-VIToolkitEnvironment.ps1) but it doesn't do a Connect-VIServer.

Re: How to list delta files in all datastores

Skark166 — Tue, 14 Oct 2008 17:04:32 GMT

I always use this to initialize the toolkit:

$vmsnap = Get-PSSnapin vmware* -ErrorAction SilentlyContinue
if ($vmsnap -eq $NULL) { Add-PSSnapIn -Name VMWare.VimAutomation.core }
Initialize-VIToolkitEnvironment.ps1

Re: How to list delta files in all datastores

LucD — Tue, 14 Oct 2008 17:03:31 GMT

The message says you are not connected.
So perhaps add a Connect-VIServer at the beginning of your c:\deltachk.ps1 script.

Can anyone see what I'm doing wrong in thepost above?

Thank you...Mike

Re: How to list delta files in all datastores

kastek — Wed, 08 Oct 2008 20:20:22 GMT

Perfect...thanks again...but...when I run the following commands separately from the Powershell command line they work fine...

Add-PSSnapin VMWare.VImAutomation.Core
"C:\Program Files\VMware\Infrastructure\VIToolkitForWindows\Scripts\Initialize-VIToolkitEnvironment.ps1"
Add-Module "C:\Program Files\VMware\Infrastructure\VIToolkitForWindows\coreModule\viToolkitExtensions.psm1"
Connect-VIServer -Server 192.168.xxx.xxx -User xxx -Password xxx
Get-Datastore | get-tkedatastorefile | where { $_.Path -match "delta" } | format-list * > c:\deltachk.txt

...but when I run them inside a script using "PowerShell.exe c:\deltachk.ps1" I get the following errors...

Get-View : 10/10/2008 11:28:32 AM Get-View You are not currently connected to any servers. Please connect first using Connect-VIServer or one of its aliases.

...what am I doing wrong???

Thank you...MIke

Either pipe the output into

format-list *

or you can pipe it into

select Path, Modification

Re: How to list delta files in all datastores

kastek — Wed, 08 Oct 2008 19:58:13 GMT

Wow...that was easy...thank you very much.

Is there an easy way to have the output not truncate, so I can see the whole Path and Modification fields?

Path Size Modification Datastore

This is pretty easy with the VI Toolkit Community Extensions.

If you use that, you can run

get-datastore | get-tkedatastorefile | where { $_.Path -match "delta" }

to find these files.

The extensions require PowerShell 2 CTP2. If that's a non-starter for you for some reason the script code should at least tell you enough to get started.

How to list delta files in all datastores

kastek — Wed, 08 Oct 2008 16:06:09 GMT

I've recently found the VI Toolkit and have learned a lot from these forums.

I'd like to be able to search the contents of all datastores for the existence of any delta files, indicating the presence of lingering snapshots...old or new.

I'd like to see the paths, filenames, sizes and dates of any delta files.

Can anyone point me in the right direction?

Thank you...Mike
