I'm using ubuntu 12.04 and have two disk partition named: /dev/sda and /dev/sdb.
my home partition and other programs are in /dev/sda. therefor any work like database benchmark on my mysql databases will do IO Transactions on /dev/sda.
I'm going to do (or redirect) this IO Transactions on(to) /dev/sdb. my search results show that i should copy my myql folder to /dev/sdb and then using symlink create a symbolic link from mysql to new mysql in /dev/sdb.
first of all, does this solution is correct? if so, how can i exactly do that? and what should i consider(such as using cp or rsync command for copy files.)?
here is symlink for mysql.
