The buffer_pool_size parameter should be a integer value when followed
by a memory unit (eg '1024M', not '1024.1M'). Otherwise the MySQL

Usage:

  galera:
    master:
      innodb_buffer_pool_size: 1024M
    slave:
      innodb_buffer_pool_size: 1024M

If innodb_buffer_pool_size is not set then 35% of the available
ram will be allocated for the buffer pool.

The tag is equal to the address of the server which is quite useless
when using a Unix socket address.
