Powershell Command to get disk space used by SiteCollection returns null

Question

I am using the following powershell command

 

$used = (Get-SPSiteAdministration -Identity "https://myspfarm/sites/testsite").DiskUsed

However when I type in $used it just returns blank. I can confirm that my URL is correct!!

Also, if I change the command to some invalid URL then I get an error

but still $used is blank.

Why??? is there a bug in SP2010? if you have a https site, could you please test this command out?

PS: I have right clicked and "Run as Administartor" for launching the SP2010 Powershell window.

Answer 1

to make matters more funny... its not that this powershell command is returning me null

If I type

$test = (Get-SPSiteAdministration -Identity "https://myspfarm/sites/testsite" -Regex)

then do a

$test | Get-Member I see

PS C:\Users\user1> $test | Get-Member


   TypeName: Microsoft.SharePoint.Administration.SPSiteAdministration

Name                      MemberType Definition
----                      ---------- ----------

ApplyWebTemplate          Method     System.Void ApplyWebTemplate(string strWebTemplate)
Delete                    Method     System.Void Delete(), System.Void Delete(bool bDeleteADAccounts), System.Void D...
Dispose                   Method     System.Void Dispose()
Equals                    Method     bool Equals(System.Object obj)
GetHashCode               Method     int GetHashCode()
GetType                   Method     type GetType()
ToString                  Method     string ToString()
AdministrationSiteType    Property   Microsoft.SharePoint.SPAdministrationSiteType AdministrationSiteType {get;set;}
AverageResourceUsage      Property   System.Double AverageResourceUsage {get;}
CurrentResourceUsage      Property   System.Double CurrentResourceUsage {get;}
Description               Property   System.String Description {get;}
DiskUsed                  Property   System.Int64 DiskUsed {get;}
LockIssue                 Property   System.String LockIssue {get;set;}

 

So $test variable not null.

But If I do

$test.DiskUsed

$test.Title

$test.Url

everything is blank!!

$test.FakeVariable is blank!!

 

 

Answer 2

Does the site collection have a quota assigned to it?  I know that in the UI, you can't see that info unless the SC has a quota.  I would try that.

Answer 3

I went and set the "Individual Quota for my site collection to 100000 MB

but still all properties of (Get-SPSiteAdminstration -Identity "https://myspfarm/sites/tessite") are empty

 

Answer 4

I solved the issue myself. Before I execute anything, I should say

Start-SPAssignment -Global

after this the script published above worked correctly.
