Here's an easy feature nobody has mentioned so far, and from my reading isn't supported: separate journal, like Ext3. The journals stay per-node, but they can be on a different (shared) volume than the filesystem proper. This should be dead simple to do and it can make a huge difference to write latency, by putting the journals on separate spindles or (what I actually have in mind) in NVRAM. Regards, Daniel
