it just like disk quota ,but not just this, it also can based on directoy quota.

What specifically is your question?

Look at the virtual file system section... maybe that will do what you want..

sorry for my english.
i just want: directory quota ,not user disk quota.

thanks ,but it not.

No apologies necessary Maybe the "quota" command might give you what you're looking for. For more info: Good luck with it

thanks,but it can't be directory quota without system user and group.

try to put your requirements using an example, that might help us in understanding what u want

Jay

example:
i have two site:
www.test1.com /home/guest/site/test1.com/
www.test2.com /home/guest/site/test2.com/

i want that /home/guest/site/test1.com/ has 20M max size,
and /home/guest/site/test2.com/ has 40M max size

but i do not want disk quota with a system user or group,
i need directory quota on linux.
ser-u and proftpd has directory quota,but only for itself,not for system.

Making each of those a virtual filesystem and allowing everyone access I think would meet the requirements.. but if you don't agree that's a workable solution, best of luck to ya.

thanks, it is a good idea. i will try it.

a new trouble, when i have many sites. it is not easy to manage, and it is slowly.

There may be some tools out there for that. You might want to start searching on sourceforge & freshmeat.

Alternatively, you could try implementing this yourself. Using the "du" command, it's fairly easy to derive
the total size of a directory. If this exceeds a certain quotum, then you could take additional action like sending e-mail warnings to you/administrators, or disabling write access to the website directories (ie via directory permissions). Put all that into a script and make it run, let's say once every 5 minutes via cron.

Thanks, I had been searching it. "du" command is not a good idea. I am looking for a "directory quota" software, it is just like disk quota. And it should be easily managed with congfigure file.

As you reject the virtual directory solution which seems to be the only one available with Linux, you may want to have a look at Solaris ZFS which allows easy to manage quotas.
