I've been running OMV for about a two months now. In the last fews days, I started getting error that the disk which OMV is running on get completely full.
I am running OMV as a virtual machine in ESXi. The OMV VMDK is 16GB and it is on a physical SSD. I have another 4 drives in my server, all EXT4, a total of about 6TB. Last I checked the fullest one had about 30% free. When this first happened i was running CouchPotato so i assumed it was writing to the wrong disk and therefore filling up the OMV VMDK and not the actual drive it was supposed to. I reverted to an earlier snapshot and the issue was gone. I then just let the server sit for about 4 days and the same thing happened. I haven't ran any downloads or added any data to any of the drives.
The error I get from ESXI is this:
Message from batman.home: There is no more
space for virtual disk

volume, and clicking button.retry. Click

I just ran df -h and it looks like somehow all the drives are filled to capacity. [Screenshot](http://i.imgur.com/PvinhsN.png) Has this happened to anyone else? Is there a way to look inside the vmdk to see what's eating up all this space? This seems like a bug but I am not sure if it's with ESXi or OMV
