This is the development site for several related linux clustering components.
Openais is an essential part of most of the work here; openais development and information is located at http://openais.org.
cluster3
unstable third generation code
cluster.git master branch: http://git.fedorahosted.org/git/cluster.git?p=cluster.git;a=shortlog;h=refs/heads/master
- use with kernel.org releases, generally current stable release, sometimes -rc
- use with openais unstable/devel
current release: cluster-2.99.12 or (alternate url) cluster-2.99.12, use with corosync svn r1677, openais svn r1656 and linux-2.6.27 (porting to new corosync is in progress).
components include:
- gfs kernel module and userspace utilities
- gfs2 userspace utilities
- dlm userspace utilities
- cman (cluster infrastructure, various pieces)
fence (i/o fencing)
