[Users] df showing zero space used

[Garith Dugmore]

Hello fellow openvz users,

Would anyone know why a 'df -h' is showing zero space used?

proxy:/var/cache# df -h
Filesystem            Size  Used Avail Use% Mounted on
simfs                 100G     0  100G   0% /
tmpfs                 2.0G     0  2.0G   0% /lib/init/rw
tmpfs                 2.0G     0  2.0G   0% /dev/shm

I've done some searching around and have had no luck finding a solution 
yet and seems to only be this container ('df -h' is giving correct 
results in other containers).

My config for that container (excluding ip,dns config):
