I work in an Enterprise environment, and in general once a RHEL release goes out of support it is time to replace the hardware anyway - We usually stick to a 4-5yr max lifecycle for hardware, which fits well with the RedHat 7yr support model. Assuming you are running non-RHEL software, an upgrade between major versions has to be a complete mess, if not impossible. Back to the original posters query - What's your business requirements? I've learned that if you try to build a solution by putting technology first it never seems to work well. We don't even know if Gluster is appropriate for your needs. David
