I've done this in the past, and it's pretty straightforward. What I did
was the following:
1. Stop mysql
2. move the mysql data dit onto the new drive (/var/lib/mysql in my case
(I'm running Ubuntu))
3. create a symlink in the old location pointing to the new location
4. Start mysql again.
One gotcha with this for me was Apparmor. This prevented mysql from
starting. I just uninstalled it instead of reconfiguring it because I
didn't need it. I don't know if Fedora uses apparmor (or similar tools
like selinux) by default, but worth being aware of. It took me quite a
bit of head scratching before I spotted apparmor getting in the way.
An alternative approach that would avoid the apparmor issues would be to
use a bind mount instead of a symlink.
