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 ?

If you have access to OpenVZ physical node you can create loop device and mount it to VPS. But you can't use loop from OpenVZ VPS because technology restrictions.
As another solution you may call your administartor/hosting provider do something like this: http://www.stableit.ru/2013/11/how-to-mount-multiple-disks-to-openvz.html
