[ceph-users] Kernel, Distro & Ceph
All; There's been a lot of discussion of various kernel versions on this list lately, so I thought I'd seek some clarification. I prefer to run CentOS, and I prefer to keep the number of "extra" repositories to a minimum. Ceph requires adding a Ceph repo, and the EPEL repo. Updating the kernel requires (from the research I've done) adding EL-Repo. I believe CentOS 7 uses the 3.10 kernel. Under what circumstances would you recommend adding EL-Repo to CentOS 7.6, and installing kernel-ml? Are there certain parts of Ceph which particularly benefit from kernels newer that 3.10? Thank you, Dominic L.
