GULM Project Page

Introduction

GULM is a server-based unified cluster/lock manager for GFS, GNBD, and CLVM. It can be used in place of CMAN and DLM. A single GULM server can be run in stand-alone mode but introduces a single point of failure for GFS. Three or five GULM servers can also be run together in which case the failure of 1 or 2 servers can be tolerated respectively. GULM servers are usually run on dedicated machines, although this is not a strict requirement.

GULM consists of userspace programs and a library.
GULM depends on CCS and Fence.
