Thanks a lot, this enlightened my mind.
Replicated Murder seems to be a good thing if you have a cluster file systems (you have mentioned GFS, QFS and CXFS, does anybody have experiences with them?). I guess NFS still doesn't come into the picture, because of the mmap behaviour...
The client that I wrote the replicated code for is using Sun's QFS. The project is currently on hold because of locking issues with QFS. I know Sun has been working with them, but I don't know where this stands.
I haven't tested SGI's CXFS with Cyrus yet, but it works very well in high-end video and post-production environments, so I don't think it would have a problem with Cyrus. Last I checked, CXFS still required an IRIX box to be the meta-data master for the CXFS cluster. I'm not sure if they have the meta-data master running on Linux yet, although the client code has been on Linux for a while.
I've never used GFS, so I don't know if it handles file locking and memory mapping sufficiently for Cyrus.
