THE SETUP

I'm running Linux CentOS on an Amazon EC2 instance.

The MySQL data files are on an EBS Drive mounted at /data/ ( symlink - /var/lib/mysql >> /data/mysql ).

Everything works fine in this setup.

THE PROBLEM

I'm trying to move everything from this EBS drive to a new drive. I umounted the /data/ drive, and mounted it at /data2/. Then I mounted the new drive at /data/ and copied everything over to it from /data2/. Everything on the system works great, except MySQL. Every time I try to start the MySQL daemon ( /etc/init.d/mysqld start ) I get a MySQL Daemon failed to start error.
