In that case it's probably best to stick with the latest kernel that has been released by the distributor for that particular distribution version. Upgrading to newer kernel versions can be tricky, if they require new userland utilities for managing new features. > But maybe I'm in wrong thinking that latest major kernel not in the > default repository is likely say "dev distribution" and instead is just > a stable release as like every others. It's in there for a reason ;) For running Ceph (on the cluster side), a latest and greatest kernel version is not really required, as the Ceph services run in userland anyway. The only requirement that I could think of that might benefit from running a more recent kernel is using the kRBD or CephFS modules, but these are "client drivers" - no need to upgrade the kernel on your entire cluster because of that.
