I have a RHCS currently on RH 4.8. My question is 3 part. Is it possible to join a RH 5.4 cluster machine to a 4.8 cluster? If not, is there any upgrade path that does not compromise the data? IOW, could I take the backend storage currently running on the 4.8, and connect it to a new 5.4 without data loss? Or, can I do an "upgrade" of the existing cluster machines from 4.8 to 5.4?
