Yes, GFS would be nice. I've also been waiting for a beta of Veritas' = CFS for Linux since December '03, but it's still a no-show.

I haven't messed with OCFS since v1.08, but it indeed was scary then. = It flat out refused to work under RH9 (AS2.1 wouldn't support our = hardware and we didn't want to spend $ on AS3), until I hacked it with a = modified RH9 patch for JFS. Like Oracle says, OCFS is only meant to = handle Oracle datafiles for RAC and nothing else. And they mean it. = Oracle PIO performance was so bad (~1M/s), that I dumped OCFS in favor = of raw. I did see a presentation of Wim's on OTN about some tips on = implementing OCFS that I didn't do, such as the OCFS versions of cp, dd, = etc., but I don't see what that would have to do with Oracle PIO = performance.

I see that OCFS has newer versions now. Perhaps it performs better now, = or perhaps it's just easier to get it to perform. If you want RAC to = install easily (and probably run like it was meant to), try it out on = OpenVMS. Has anyone here tried RAC on an OpenVMS cluster? It looks = (*looks*) like it's a no-brainer setup, thanks to the most mature and = stable clustering around. :)
