Reclaim thick provisioned space

I've got 5 VM with thick provisioned disks of various sizes on a datastore.

I'd like to reclaim some of the wasted space I provisioned on this host. Is there a way I can tell ESXi to reclaim unused space once I boot off a G-parted disc and reduce the partition size of the VM's? Is there any other way to do it? I only have a couple GB's left on the datastore.

TIA.

I am not sure if you can do that with GParted on ESXi ... you could try using VMware Converter to move a VM to a Windows PC and then convert it back to ESXi using thin provisioning. I'm assuming that you have plenty of free space in your thick provisioned VMs right?

mikelane is correct, convertor is the best tool to recalim the space from thick provisioning disk.

With a partition program you will not change the vmdk size, but only the partition size inside the VM.

As written use the Converter.

Couldn't you just *clone* it and use thin-provisioning on the target? That seems far preferable (and less prone to errors) than going from V2P and then back P2V.

So I assume you have no access to vCenter? You could just use sVmotion to do it. Other way would be converter as already pointed out.
