Do we need to replace heartbeat with keepalived, or can they both be on the CD allowing individuals to choose between the two? - BS > Hi DL-Developers, > > > I have recently switched from heartbeat to keepalived for my LVS-director > software on the latest DL. > > > From the homepage: > > What is Keepalived ? > > The main goal of the keepalived project is to add a strong & robust > keepalive facility to the Linux Virtual Server project.
