Reclaiming Space in a volume and LUN

Currently Being Moderated

Good afternoon all,


I was asked a question this morning that I wasn't sure how to answer...


The following is our situation:


This is regarding using a FAS3240 in a virtual environment (vSphere).


I am looking at the NetApp tab in vCenter (VSC4.1)

I select on of my datastores and see the following (picture attached):


DataStore Usage (19%)

LUN Usage (60%)

Volume Usage (48%)

Aggregate Usage (62%)


A few facts:

From Virtual Centre, it looks like I have 81% free space on my 2.7TB LUN

From NetApp console, it looks like I onjly have 40% free space on my 2.7TB LUN


My assumption is the following:

The reason the LUN usage is @ 60% is because at one point in time, that LUN was 60% full.

Using Storage vMotion, much of that data was relocated to another LUN or DataStore.

There is a lot of 'white space' on that LUN.



Is there a way to recuperate that whitespace ?

NOTE:  Deleting the LUN and Volume and re-creating will do it but this is not efficient.
