"Thick" Provisioned NFS Share

Ekuskowski used Ask the Experts™
I created a Windows Server 2016 and created an NFS 3.0 share. I am using this NFS share for vcenter 6.5 to connect and use as the primary datastore.
My problem is vCenter says the NFS share is strictly set to accept only Thin Provisioning.
How do I change my NFS share to also accept "Thick Provisioning" of Disks ??
I now have a few TB of data on the NFS share so hopefully this can be changed without losing the current data.

Is this a lab? I wouldn't use regular Windows to host any VMs over the network unless it was a scale out file server for Hyper-V. I wouldn't use native Windows iSCSI target and I sure as heck wouldn't use it via NFS for VMware datastore. Wrong tool for the job.

What is the ultimate goal here for your VMs. I feel like you need to make some changes to the architecture.

You have to do that on a per VM basis. You will need to look at the properties of the VM and change it to thin provisioning. This may require you to power off the VM to set it, an you will not loose your data. By default NFS stores will use thin provisioning, or you can change it when you create a new VM. Select thick instead of thin when you create the VM, but if the VM already exist you will need to look at the properties or the VM and look at the drives and it will allow you to change it, but it will most likely require you to power off the VM to make the change.


Thank you both for your answers,  I'll continue with the NFS for now. I'll look to change to an iscsi target later.  
I'll change all my VMs to be thin provisioned as that will alleviate my problems for now
