Restrictions on the MySQL Database Directory

Regardless of which MySQL delivery method you have chosen, that is from http://www.mysql.com or from other source, the following restrictions apply.

Each MySQL instance must have a unique Database directory. You can mount this Database directory as either a Failover File System or Global File System.

It is always a good practice to mount the Global File Systems with the /global prefix and to mount the Failover File Systems with the /local prefix.
