Yes, you certainly needs to chown the files to the specific user id's for filesystem quota to count the files in the user's quota.
This will solve your quota needs, although I see many potential problems: - The mysql daemon needs to have access to the files. An easy solution is to chgrp mysql the files (they should already be) and then change the permissions so the group has access to them (chmod g+rwx). You could also use access control list if your system supports it. - We don't want the users to access the database files directly If a user owns a file, he can change permissions on it, modify it, delete it, etc.. The mysql daemon will not like that and it can cause all sorts of unexpected problems I guess. So the first thing to do is to NOT put the files in the user's home directory with the symlink hack. This has no advantage and the users will certainly mess with them if you do so. A complete solution might be to only chown the files, not their directory. If the user has no access to the directory, he cannot modify its files even though they are owned by him. - Database files are created at various times You cannot only have a script set the permissions correctly when the database is created and then forget about it. As the tables will be created, new files will appear and they need to be chown'ed / chmod'ed. A cron job might come in handy here. - innodb tables are different This should work with myISAM tables, but innodb stores the data in one big file shared between databases if I am not mistaken. So you need to prevent your users from using innoDB. May be other table type will have a similar problem and you might not be able to prevent users from using them. May be someone more experienced with the different table types available can enlighten us here. I never tried such a setup but I will have to soon. Any quirks I missed?
