HI All
I have a strange issue.
We have a several vm's who's disk I have been told are thick, but everything I can see suggests they are thin.
Within the datastore of one of the disks it show the following: Size and Provisioned, that to me shows the disk is thin.
Not sure why the size is showing all the same as provisioned, whilst the OS which is Linux states only 52GB is being used out of the provisioned 100GB
When your right click on the vmdk you get the option to Inflate the disk, this also points to the disk being Thin Provisioned.
As per my understanding, the inflate option should be greyed out, if they vmdk is thick provisioned.
When you right click the vm and select edit it also shows the disk as being thin
Has anyone seen a issue similar to this before or can help clarify if my argument of the disk being thin is correct or not.
Thanks
Jit
As per your screen shots, disks are THIN provisioned. If disk is THICK you do not get "Provisioned size" column (ref-first screen shot). I assume you are using VI client.
Also you do not get "inflate option" if disk is THICK. You are correct.

Has anyone seen a issue similar to this before...
I see something similar from time to time..
The disk lives on a NetApp NFS datastore where no VAAI is involved.. So no way it can be Thick Eager. The discriptor file for that .vmdk also has ddb.thinProvisioned = "1" value there, so I'm sure it's thin..
Never bothered to look further into this, but I've seen this on ESX 4 and ESXi 5.x...

Thank you Vicky I was sure I wasn't going crazy.
I think we could be suffering from white space issue, where by deleted data within the thin provisioned disk is now showing correctly.
Once again thank you for your help and proving im not going crazy![]()
Thank you Rubeck much appreciated.![]()
Rubeck how can I check the disk descriptor file to see if it has a value of 1???
By using SSH or console access if available..
