Thank you for stopping by but just as a heads up, this post is not VMware virtualization related. After a bit of hardware trouble from the local store, my replacement flight sim rig is up and running Lockheed Martin Prepar3D 4.
I want to take some time to dive into some new core storage features that might be somewhat less heralded. There are a couple of enhancements in space reclamation in ESXi 6. This is the big one.
It is finally back! The default is on. You can also configure it with esxcli: Now there is a bit of confusion with the settings here.
My sources at VMware tell me that only low is currently implemented in the kernel, so changing this to anything but none or low will not affect anything at this time. So keep an eye on this.
I need to officially confirm this. Meaning space is not reclaimed as soon as you kick off the delete. If you want immediate results, your handy esxcli storage vmfs unmap command will do the trick.
Instead they have introduced a crawler, that runs on each ESXi hosts that on certain intervals will run reclamation on datastores to get space back. This is not immediate in any sense.
Expect to see results within a day or so. The nice thing is that, dead space will be taken care of—you do not need to worry about it any more from a VMFS perspective. So how can I tell if it is working? Well since it could happen at any time, this is a bit tougher.
Of course, watching your array is an option. Is space going down? If yes, it is likely to be working.
Num from heap pool: Vsish is not technically supported by VMware, so I am looking for a better option here. See this from VMware KB So what are the requirements to get this to work?
Well there are a couple of ways. Of course you can check the above requirements. But how about from the guest?

· Thin provisioning is a file system feature, and with copying the files using tools which are not aware of this, the files will inflate again. If you are copying virtual disks from VMFS datastores to other VMFS datastores use the vmkfstools command line utility.
