apparmor will block mysql from read/write other directories, you should configure it at: /etc/apparmor.d/usr.sbin.mysqld
well thanks, this thing had me reinstall my complete server...
congrats, I would recommend a reboot after setting up the database that way ^^ ... not!
You can even export just one schema (subfolder)! Apparmor must be modified.

Hi, have any idea why this isn't working for me? Basically mysql claims that it can't write/read the files in the directory. Could have some permission type error with ramdisk?
