Linux-HA and heartbeat

http://www.linux-ha.org/

The goal of the Linux HA project is to provide 'a high availability (clustering) solution for Linux which promotes reliability, availability...'

The Linux-HA project's main software product is Heartbeat, which is a cluster management program for high availability clustering. Some of the features of heartbeat include:

- no fixed number of nodes
- resource monitoring
- fencing

Linux-HA state that their software (Heartbeat) is well integrated with separate projects like LVS and DRBD

Heartbeatv2 can do resource monitoring of Lustre for example, by using /etc/init.d/lustre with the 'status' argument (I think it looks in /proc or /sys), see https://mail.clusterfs.com/pipermail/lustre-discuss/2005-September/000870.html
