This is INHERENT to the way Berkeley Fast File System works. It reservees 10% for performance improving scratch space and other things. Using this 10MB of disk space causes serious performance degradation. >So, how to I fix this? If you don't like it, write a new filesystem that doesn't do this, otherwise, live with it. [There techincally IS a way to reduce the amount of space the OS reserves for this stuff in a filesystem, but I would recommend against it highly]. Toodlepip!
