I have 2x 480GB SSD cache drives on my unRAID 6.3.2 system. You can see how they look in Main from the attached screenshot. On my cache are appdata, one (1) Windows 10 VM using a 150GB disk image, and pretty much nothing else. I've also attached a screenshot of the directory listing with the VM disk image in it for comparison (it's the biggest thing on the drive).

 

Here's where I'm confused:

 

The disk image is 150GB.

Linux shows 161061273600 on disk.

My cache drive only shows 112GB Used (just ran a balance in case it was messed up some how, and nope, that's all that's used as far as unRAID is concerned).

 

Any ideas?

 

Vdisks are sparse.

Ahhhhh. And so that's the "Allocation" amount, then?

Yep.
