High-Availability

[Andrew G. Hammond]

LVS + keepalived will solve the problem you described below. What are 
your scalability needs / availability needs that you require such a 
heavy duty solution? What I would suggest is that unless you really do 
need very high performance and scalability, simply go with a pair of 
servers and use VRRP (supported under keepalived) to provide a redundant 
IP. Then mirror data between master and slave filesystems using either 
CODA or whatever other approach suits you. This is not true HA, but 
should be sufficient for most needs.
