Folder size quota in FreeBSD?

[technobeast]

I have N (certain count) folders in a FreeBSD server. And N users logging into their own folders (no local accounts web interface only - PHP script). Any idea how to give a folder size quotas for each of the folders? FreeBSD 5.1. Should this be done via FreeBSD or with the web interface - the script. I have root account to the server.

uhm. I don't get it.

Is this a filesystem quota problem? (are the users local unix users?) Or is this an application quota problem (virtual users, with virtual quotas)

I assume it's the latter, then you can do anything that your creativity feeds you to limit users in their usage.

Yup it's the latter. The guy that made the software for our company couldn't do it via the script (site) and I have to figure out a way to do it with the OS. But since I don't have a real user access, with a web site and file manager (php script) to it, I was confused in searching a way to limit the quota.

you can't do it with the OS. just do it with PHP.

It's a bit ugly and expensive, but you can call du -s <dir_root> and parse the output (in bytes) such that you do not allow more uploading, etc. when the value exceeds a soft limit. You have to see whether it is too slow or not, either use a database to keep track of the files and their sizes (SELECT sum(size) FROM files WHERE owner=$userid; you get the point)
