Not sure very many people really have. So this is generic CFS discussion, not drbd related: Ignore OpenGFS. For details, read the wikipedia entry http://en.wikipedia.org/wiki/Global_File_System Lustre is not really designed for small clusters. ie. you implied 2 nodes. Lustre is for many more than that. So I think it is a choice of ocfs2 vs. gfs2 OCFS2 has been in the vanilla kernel for a year or more, but it is missing some basic features you may miss. ie. no ACL support and I don't think it supports file locking. It was really designed to offer just the functionality that Oracle needed for a clustered Oracle DB setup. See the metadata table at http://en.wikipedia.org/wiki/Comparison_of_file_systems GFS2 has also been in the vanilla kernel for a year or more and is more of general purpose FS. But since it is a Redhat developed FS, I suspect you won't find much distro support outside of Redhat. And you failed to mention a intriqueing possibility. OpenSSI and it its CFS. They do have drbd integrated into that. I'm not sure how stable that environment is. I also don't know if that CFS is active/active, or more the traditional active/passive drdb setup.
