For what you want you need a disk server/linux cluster box of some kind, maybe with high availability raid.
Then, allow both servers to process read & write. When one fails the other is there by default. The disks are already there, mounted, served out by another box, so they do not have a failover problem.
This also solves the 'out of sync' problem.
This is almost exactly what everybody with a SAN is doing right now. Except for orders of magnitude lower cost. Our SAN costs us $US40 per MB; a PC with SATA can have a MB of raid for 2 orders of magnitude less. Circa $US1.00 - $US2.00 per MB.

MYSQLD(8) MySQL Database System MYSQLD(8)
NAME
mysqld - the MySQL server
SYNOPSIS
mysqld [options]
DESCRIPTION
mysqld, also known as MySQL Server, is the main program that does most of the work in a MySQL installation. MySQL Server manages access to
the MySQL data directory that contains databases and tables. The data directory is also the default location for other information such as
log files and status files.
When MySQL server starts, it listens for network connections from client programs and manages access to databases on behalf of those
clients.
The mysqld program has many options that can be specified at startup. For a complete list of options, run this command:
shell> mysqld --verbose --help
MySQL Server also has a set of system variables that affect its operation as it runs. System variables can be set at server startup, and
many of them can be changed at runtime to effect dynamic server reconfiguration. MySQL Server also has a set of status variables that
provide information about its operation. You can monitor these status variables to access runtime performance characteristics.
For a full description of MySQL Server command options, system variables, and status variables, see Section 5.1, "The MySQL Server". For
information about installing MySQL and setting up the initial configuration, see Chapter 2, Installing and Upgrading MySQL.
