Of course they can be, otherwise clustering wouldn't be possible at all. > You need some extra > software running on some Linux systems (either Linux on the z or Linux > on another platform) to support some sort of clustered file system > (e.g., AFS, GPFS, etc.). If you really do mean read only access for everyone, then I would probably be looking into using iSCSI for every guest that requires access to it, with the one guest that "owns" the LUN using the normal SCSI over FCP.
