High-Availability Linux Project
(Linux-HA) aims to:
"Provide a high-availability (clustering) solution for Linux which promotes reliability, availability, and serviceability (RAS) through a community development effort.
The primary software product from Linux-HA is called heartbeat.
"implements serial, UDP, and PPP/UDP heartbeats together with IP address takeover including a nice resource model including resource groups. It currently supports multiple IP addresses and a simple two-node primary/secondary model. It is both extremely useful and quite stable at this point in time."
A number of the prominent sites using Linux-HA are listed on the
Heartbeat Success Stories page.
Version 1.0.1 of heartbeat
has been announced,
this version is:
the first major stable release of the
Linux-HA project since March 2001, and the culmination of a long series of
successful beta releases.
The major features in this stable release include support for many new
STONITH devices, an application monitoring subsystem, unicast
communications, standby capability, IP connection montoring (IPfail)
feature, improved realtime performance, CCM membership subsystem, ability to specify fractional seconds in times, *BSD and Solaris compatibility,
documentation improvements, extensions to heartbeat client API, etc.
