I was looking for a way to store my mysql databases on a different partition than the default installation. I found this link and followed the steps.

However, after having changed the line datadir = /var/lib/mysql in my.cnf to datadir = /storage/mysql-data, I find myself unable to start the mysql service again:

pieter@foxbox:~$ sudo service mysql start
start: Job failed to start

When I change the datadir back to the standard value, it does work again. Why? What is the problem with the solution in the link?

I'm on Ubuntu 12.04, 32bit

Did you move all files from /var/lib/mysql to /storage/mysql-data before starting mysql ? Also, check that the permissions of the new directory are the same as those of /var/lib/mysql

Only the folders corresponding to databases. – Honoki May 19 '12 at 12:36
