Cannot start replication on slave

[Alex Recarey]

Hello all,

I have scoured the internet and forums before posting this, I appreciate the time taken to read this.

I have previously setup a master-slave replication from 0. I am now trying to do it in a working production system.

I lock the masters tables with FLUSH TABLES WITH READ LOCK, and take note of the status with SHOW MASTER STATUS. Before unlocking the tables, I make a full copy of the databases into the slave using mysqldump. I then execute UNLOCK TABLES.

When I get to the slave, and try

RESET SLAVE;
STOP SLAVE;

CHANGE MASTER TO
MASTER_HOST='XXX.XXX.XXX.XXX',
MASTER_USER='XXX',
MASTER_PASSWORD='XXXXXX',
MASTER_LOG_FILE='master-bin.000005 ',
MASTER_LOG_POS=18262972;

I get the following error:
ERROR 29 (HY000): File '/var/lib/mysql/master.info' not found (Errcode: 13)

If I try adding the master.info file by hand, with the following permissions:
-rw-rw---- 1 mysql mysql 0 2009-05-28 02:41 master.info

I get the following error:
ERROR 1201 (HY000): Could not initialize master info structure; more error messages can be found in the MySQL error log

The MySQL error logs are empty.

What can I do?

Thank you
