I am trying to move my existing mysql database to drbd file system, which is in turn replicating to another node.<br>I shut down the db. edited the my.cnf file and updated the datadir to<br>datadir = /var/lib/mysql_drbd<br>
and<br>log_bin = /var/lib/mysql_drbd/mysql-bin.log<br><br>I copied all the files under the
default mysql directory to this new drbd files.<br>set the permissions to the new file system to chown mysql:mysql /var/lib/mysql_drbd<br><br>started the db using service mysql start. it just crashes. but if I change the path to the original location it starts working fine.<br>
