failover mirror - enbd good solution?

Hi!

I need to setup two servers, one running mysql, the other apache+php. If
one of the servers dies, then i need to run the two application on the
survivor.

I played with ENBD before (cca. 2 years), and as i recall, enbd is a good
solution for the data-syncing.

My idea is a raid1 (fr1) between the two machine, mounted on machine A,
and mysql running on the fr1 device. If machine A dies, then machine B
stops the fr1, mounts the remaining half as a "half legged" raid1, and
start the mysql on machine B.

ENBD is good for me?
