Pessoal, gostaria que alguém me desse uma luz, por favor, para resolver o seguinte problema: preciso de uma forma de limitar o tamanho de um diretório, mas sem utilizar cotas de grupos e usuário... será que existe uma forma eficaz e prática?

Por exemplo, quero impedir que o diretório X fique com mais de 100MiB, independente de quem tem acesso a ele...

Será que em último caso seria possível criar um usuário somente para controlar o tamanho da pasta X? Será que colocando esse usuário como owner da pasta, e liberando todas as permissões de escrita, quando alguém escrevesse na pasta consumiria a cota desse usuário e assim seria possível impor um limite máximo para uma pasta em particular?


obrigado desde já

According to Google translate, it goes something like this:
It's a lousy translation, but it looks as though gustavolinux would like to use quotas.

You could mount the directory on a partition that is only 100MB in size.

Friends, could anybody there give me a light, please, to solve the following problem: I need a way to limit the size of a folder, but without using group or user quotas... is there a good solution?

For example, I want to avoid that folder X grows up more than 100MiB, no matters who writes to the folder...

If there is no such way, maybe do you think that it is possible to create a new user account just to control the size of the folder X? I mean to put this new user as the owner of the folder X and allow any access to the folder... Do you think that, if someone writes to the folder, the quota of the new user would be consumed and reach an unbreakable limit?

thanks in advance

folks, ahead I tried to write in english... sorry, sometimes I get a little confused about what forum uses what language...

the idea of the partition is ok, but a little hard to change right... resizing a partition takes time, right?

is there a better solution with UID or GID?

thanks for the attention

Folks, I need to limit the size of a folder shared in the network, no matters who have access and write to it... in other words, think about a folder that every user have to

access and possibly write, but the size of this folder has to be under a size limit...

In my concern, there is no configuration mecanism especially made to this task, right? I think that the proper feature should come from the filesystem...

But, anyway, I thought about a solution using group quotas. I guess that when you enable the folder's setgid bit, everything that is copied to that folder becames owned by the folder's group owner. If I create a group of users, let's say named "Control", and put every network user in this group (but as a secondary group - "Control" won't be the main group of no user), do you think that the "Control"s group disk quota (properly configured) will limit the size of the folder (without limiting no user's quota)...

Is there a chance that this idea work? Is there a better choice?

Thanxs in advance....

just to give a feedback: a loop device was a really good idea... to every folder that I want to limit its size I create an image of a file system with the right size... []'s
