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.
Question:
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.
Thanks.
