Hi Everyone,

I have a problem with one of my VM's. I have an Ubuntu instance running on a 500GB SSD (reported total space of 476GB). The problem is that the SSD is now nearly full, with Host Windows and VMware Player both reporting 425GB used leaving 51GB free.

However, the Guest OS Ubuntu reports taking only 328GB. This was measured by Disk Usage Analyzer running as root. There's a massive 97GB disparity I cannot account for between the claimed Guest OS usage and actual size on disk. To try and fix this, I defragmented then compacted the Guest OS using VMWare Player, which freed only a very small amount of space.

Does anyone have any experience with this issue? I'd greatly appreciate some help! The last time my VM ran out of disk space it corrupted the guest OS!
