The Red Hat Cluster Manager software was originally based on the open source Kimberlite
http://oss.missioncriticallinux.com/kimberlite/ cluster project which was developed by Mission
Critical Linux, Inc.
Subsequent to its inception based on Kimberlite, developers at Red Hat have made a large number
of enhancements and modifications. The following is a non-comprehensive list highlighting some of
these enhancements.
• Packaging and integration into the Red Hat installation paradigm in order to simplify the end user’s
experience.
• Addition of support for high availability NFS services.
• Addition of support for high availability Samba services.
• Addition of support for using watchdog timers as a data integrity provision
• Addition of service monitoring which will automatically restart a failed application.
• Rewrite of the service manager to facilitate additional cluster-wide operations.
• Addition of the Red Hat Cluster Manager GUI, a graphical monitoring tool.
• A set of miscellaneous bug fixes.
The Red Hat Cluster Manager software incorporates STONITH compliant power switch modules
from the Linux-HA project http://www.linux-ha.org/stonith/.
