Release 2.0.1 of Linux-HA is available
The Linux-HA team proudly announces release 2.0.1 of the Linux-HA (aka "heartbeat") software. You can find it here: http://linux-ha.org/download/index.html#2.0.1 This release extends the capabilities of Linux-HA to be a good match to any commercial HA package. This release provides support for monitoring of resources (services) and support for larger clusters. In Release 2, simple clusters are simple to create, and more complex clusters can take advantage of our rule-based resource placement methods to ensure that the cluster does exactly what is desired when failures occur. In addition, it supports the OCF standard resource model, the SAF membership API, and provides command line, web-based and SNMP-based cluster monitoring tools. It extends our tradition of high quality through excellent code, exhaustive automated testing, zero warnings in source, and for the first time, all project code passes a static analyzer with no complaints. Many thanks to the whole crew of people who worked so hard to bring you this release! (i.e, they wrote most of the new code).
