I'm not much of a coder, so I'd like to support anyone who would like to work on this. I'll provide anything I can to help make this work. As a datapoint, I currently have a 5 node cluster running suse linux (enterprise) with Polyserve's cluster filesystem and distributed lock manager. They have two software components (well, more, but two bundles) - a distributed filesystem is the core of their software (with a distributed lock manager), and they also have an NFS bundle that allows multiple NFS servers to access and share the same data via shared storage. This is very useful to us (and many other companies much larger), and we pay a premium for it. I'm not sure what I could do, but I'm certain I could provide at minimum an environment to build/test all of this. Just curious - what are the pros/cons of porting GFS vs mangling UFS? I know GFS already has a base architected, but in the long run, what would be best? A BSD licensed fs would be completely awesome.
