VMWare provisioned space too large

I have a VM sitting on my ESXi host.  It has a 1TB C: and an 8TB D: drive for data.

In vCenter, it shows a provisioned space of 19TB.  I have no snapshots.  Let me retype...I removed the three snapshots I had.  Still, it shows 19TB of provisioned space.

How?  Why?  What?

I really need to reclaim this erroneously provisioned space.

How can I do that?

Thanks

Cliff

i have learned that the swap file was created several days ago when we first spun up the box and there wasn't enough RAM in the server and a swap file was created.  I went in and "reserved" the RAM and when it booted up, the huge file was gone.

However, there is still a disparity.  I see 19TB provisioned for a VM with an 8TB disk.

How do I reclaim this space?

When a VM is powered on, a swap file is create the same size as memory assigned in the VM.

If you specifiy a memory reservation, a swap file is create equal to the memory reservation.

Can you please provide a screenshot of your datastore and vm folder.

could you also provide a screenshot of the VM Settings, e.g. Edit Settings, Machine Disks.

What size have you allocated to virtual disks e.g. vmdk?

1TB and 8TB

are you using the new ESXi 5.5 (as previous version of ESXi were limited to 2TB disks)?

Hey buddy, glad you're on this.  This first foray into vmware in production is handing me my butt!

I read about the swap file and that's what it was...a vswp file.  So, I shut down, set my RAM to reserved, fired it up and now I no longer "see" the 8TB file.  

BUT, when I look at my datastore, it has not reclaimed the space.

That's very odd, I would refresh, wait a few hours, and then check at the console.

are you sure 8TB, that's alot of RAM to assign to a VM?
