The volume show command from the cluster shows many volumes as thin, but when I run the command in Powershell it shows them as thick.

I have used powershell Ontap modules many times and it always seem to be accurate but in this case I have tried the command from two version of the powershellOntaptools and get the same result.  This is the first time running it with this company.

Can you show the output from the ONTAP CLI and also your PowerShell output (feel free to remove identifying SVM/volume names before posting)? In the Get-NcVol cmdlet output, it's in the VolumeSpaceAttributes property in a field called "SpaceGuarantee" and will be set to "none" or "volume".  You can also find it for a specific volume by using the Get-NcVolOption cmdlet (the field is just called "guarantee" if you collect the data that way).

Okay, looks like a thin-provisioned volume to me. Can you share the corresponding PowerShell output for the same volume? 

[LisaG]

This is what it shows in powershell.

Ah, looks like a thin-provisioned volume but a thick-provisioned LUN. Can you run a "lun show <lun path>" from ONTAP and paste the sanitized output here? I'm guessing we'll see "Space Reservation" enabled for the LUN in question, which would match your PowerShell output.

Here is some documentation that explains this configuration (short version is a thin-provisioned volume containing a thick-provisioned LUN behaves like a thin-provisioned LUN):

Hi LisaG,

I noticed the "lun show" output you recently provided is for a different LUN and volume than what you originally provided. 

Original:
/vol/INWI_NEW_vnhamaptsmp06dr_Lun_7_vol_vol/INWI_NEW_vnhamaptsmp06dr_Lun_7_vol

Recent:
LUN Path: /vol/xxxxxxxxx_Lun_7
Volume Name: INWI_vnhamaptsmp03dr_Lun_7_vol

Regards,

Team NetApp

What is the proper configuration for a volume containing a LUN?
