Is CephFS a good solution for the problem I have to solve?
As a brand newbie with CEPH I'm trying to figure out if it is a good solution given the hardware I have to work with and the problem I need solve. At first look CEPH does appear to do what is required, namely a replicating file system. But it appears it might be too "heavy". The environment is 2 Ubuntu Linux servers each with 2 hard drives. They will be clustered. Nothing, other than the hardware and OS, is decided. We can create any solution that works. One of the servers in the cluster will be primary and it will fail over to the secondary until the primary is brought back on line. Does Ceph make sense for keeping the hard drives/filesystems synced? Thanks for your input.

No. 2 servers with 2 HDDs is not a sensible deployment for Ceph. Use drbd, or depending on how (a)synchronous and (de)coupled you want the instances to be, rsync with or without snapshots. -- SUSE Linux GmbH, GF: Felix Imendörffer, Mary Higgins, Sri Rasiah, HRB 21284 (AG Nürnberg) "Architects should open possibilities and not determine everything."
