Hi Nick,

I have already a setup that includes one master and several slaves that
are load balanced using Keepalived (http://www.keepalived.org). This has
served me very well for a year.

What I want now is to have a second master that would take over if the
primary master goes down, i.e. reduce the time it would take to have a new
master fully operational.

Thanks for your input on DRBD anyway.

Sam
