CMAN Project Page

Introduction

CMAN is a symmetric, general-purpose, kernel-based cluster manager. It has two parts. Connection Manager (cnxman) handles membership, messaging, quorum, event notification and transitions. Service Manager (sm) handles "service groups" which are a general way of representing and managing instances of external systems that require cluster management. The CMAN cluster manager is the foundational system upon which DLM, GFS, CLVM, and Fence all depend. The CMAN API in the kernel and userspace is general and available for other programs to use.

CMAN consists of a set of kernel patches and a userspace program (cman_tool). CMAN depends on CCS (only cman_tool which can optionally be used without CCS if all parameters are given on the command line.)
