Sorry guys. My bad.
In my case i forgot to add some flags to the partition (usrjquota=aquota.user,grpjquota=aquota.group,jqfm t=vfsv0 , i had default
). So this was my fix. In all other cases, you can fix it with this thread: http://www.howtoforge.com/forums/showthread.php?t=24366
, i think. But backup your stuff first :P
