In general, using Cyrus over a distributed filesystem isn't going to result in optimum performance. Cyrus makes use of mmap() heavily, and most network filesystems don't implement mmap() efficiently. Further, file system locking on many is either spotty or slow.
Things like Veritas or other share-the-same-disk-between-systems solutions may work better; I've never tried it, nor have I heard of any success (or failure) stories.
