On a openVZ containing Deb7 I need to lock the maximum size of a folder, which is used to upload on a php based web server. The directory is synced, so I have to lock the maxsize. MAXSIZE should be upgradable by adding some physical disk later ...

I want to use a file as a block device for a file system. So I have done :

dd if=/dev/zero of=/disk2/filesystem.dat bs=1M count=100

Then, I made the filesystem on it

mkfs.ext4 filesystem.dat

Then I tried to mount it :

mkdir /opt/filesystem ; mount /disk2/filesystem.dat /opt/filesystem

My OpenVZ (it is on a VPS) has no loop module in the kernerl. So I got

Could not find any loop device as usual under OpenVz

So i think I have to use FUSE, but I really do not know HOW ....

Any idea on locking the size of directory under OpenVZ ?
