After moving server from Ubuntu 10.10 (22.214.171.124) to 12.04 LTS (126.96.36.199). So i copied all necessary config files. Apache/dovecot/fetchmail/bind... 1) i also notified DB diference between those two versions of ISPconfig. So i used mysqldiff to apply changes to old database (add/remove fields in tables...) But just now i notified that table "sys_config" contains db_version | 188.8.131.52 and on new server it should be db_version | 184.108.40.206 So should i change it. 2) I don't get how quota works. Because when users reaches his limit (Website quota (harddisk)). There is problems creating files (as exepected). But even when users free some space up. He still cannot create files. And in panel there is still old size. I couldn't update (Website quota (harddisk)) - ISPConfig variable. I tried quotacheck -favugm but still. Only solution was to increase a limit of particular user. So question is about quota. How and when they are recalculated. Is it possible that something isn't working ?
