I'm following the HOWTO for "Setting Up A High-Availability Load Balancer (With Failover And Session Support) With HAProxy/Keepalived On Debian Lenny" and I have one quick question. How does one get the slave Apache server to mirror the master Apache server so that, on failover, the slave server becomes the master *and serves out the same identical material*? Would rsync work?
Moosefs Maybe you can use moosefs, it is realy easy to install and configure, and even to be covered from a failed master server.
