ISPConfig quota soft/hard limit

Hi all!

I'v searching for a while but I didn't find information about how does ISPConfig handles quota hard limit.
My situations is:
1st
Sites -> Website -> Domain -> Harddisk Quota: 10MB
Sites -> Statistics -> Website harddisk quota: Soft limit:10MB; Hard limit: 11MB
2nd
Sites -> Website -> Domain -> Harddisk Quota: 100MB
Sites -> Statistics -> Website harddisk quota: Soft limit:100MB; Hard limit: 101MB

Where comes this +1MB to hard limit?
Is it possible to setup quota without hard limit from ISPConfig, or I have to do it manualy every single time with 'edquota -u webXX'?

Thank you in advance.

 

I returned to this question, because I want to set hard limit to 0.

I'v found two related plugins. The first is:
/usr/local/ispconfig/server/plugins-available/apache2_plugin.inc.php
with code for quota:

PHP:

// Set the quota for the user, but only for vhosts, not vhostsubdomains
if($username != '' && $app->system->is_user($username) && $data['new']['type'] == 'vhost') {
  if($data['new']['hd_quota'] > 0) {
    $blocks_soft = $data['new']['hd_quota'] * 1024;
    $blocks_hard = $blocks_soft + 1024;
  } else {
    $blocks_soft = $blocks_hard = 0;
  }
  exec("setquota -u $username $blocks_soft $blocks_hard 0 0 -a &> /dev/null");
  exec('setquota -T -u '.$username.' 604800 604800 -a &> /dev/null');
}

So I'v created a custom plugin to change $blocks_hard to 0.
There was a problem when I tried to use "$data['new']['type'] == 'vhost'" in if() because when I changed Harddisk Quota of the site I saw these things in $data array:

PHP:

[old] => Array
  (
    [domain_id] => 220
    ...
    [type] => vhost
    [parent_domain_id] => 0
    ...
[new] => Array
  (
    [domain_id] => 220
    ...
    [type] => vhostsubdomain
    [parent_domain_id] => 0
    ...

Which is really strange for me. How can type changed from vhost to vhostsubdomain?
So now I use $data["new"]["parent_domain_id"] == "0" in if() instead of checking "type".

The second plugin is:
/usr/local/ispconfig/server/plugins-available/cron_plugin.inc.php
So my next question is that when will cron_plugin.inc.php run? Do I have to create a custom plugin for cron_plugin too, if I want to keep hard limit 0?

Thank you in advance.

 

I'v found answers to my questions, and modified my custom plugin.
I share it with the others, it somebody will have the same problem:

PHP:

        if ($data["new"]["parent_domain_id"] == "0") {
          if($username != '' && $app->system->is_user($username)) {
            if($data['new']['hd_quota'] > 0) {
              $blocks_soft = $data['new']['hd_quota'] * 1024;
              $blocks_hard = 0;
            }
            else {
              $blocks_soft = $blocks_hard = 0;
            }
          }
        }
        else {
          $parent_domain = $app->db->queryOneRecord("SELECT `domain_id`, `system_user`, `system_group`, `document_root`, `hd_quota` FROM `web_domain` WHERE `domain_id` = ".intval($data["new"]["parent_domain_id"]));
          $username = escapeshellcmd($parent_domain["system_user"]);
          if($username != '' && $app->system->is_user($username)) {
            if($parent_domain["hd_quota"] > 0){
              $blocks_soft = $parent_domain["hd_quota"] * 1024;
              $blocks_hard = 0;
            }
            else {
              $blocks_soft = $blocks_hard = 0;
            }
          }
        }
        exec("setquota -u $username $blocks_soft $blocks_hard 0 0 -a &> /dev/null");
        exec('setquota -T -u '.$username.' 2592000 2592000 -a &> /dev/null');
    }
