Maybe this is more a question about logics. I would by default always go for my default/preffered linux. Because that is what you know, can troubleshoot best, knows your team, you have made a conscious choice in the past for this etc. And deviating from this should be backed by good argumentation. Afaik the newer kernel is only necessary for ceph clients, so if you don’t do something hyper converged there is no need to get it (verify this). So first decide what you need, then see if your default setup is able of handling this. As a side note, I am running CentOS7 testcluster, installing the elrepo kernel gave me some booting problems because of the mpt2sas driver changes, but nothing that cannot be fixed with a little time an effort. There is also different kernel ofered here. But you have to search the archives where it is located. -----Original Message----- From: Massimiliano Cuttini [mailto:max@xxxxxxxxxxxxx] Sent: zondag 25 februari 2018 13:18 To: ceph-users@xxxxxxxxxxxxxx Subject: Linux Distribution: Is upgrade the kerner version a good idea? Hi everybody, Just a simple question. In order to deploy Ceph... Do you'll use a default distribution that already support recommended kernel version (> 4.4). Let's say Ubuntu. OR Do you'll use your preferred linux distribution and just upgrade it to a higher kernerl version. Let's say CentOS. ... and a bonus question: Is upgrade the kernel to major version on a distribution a bad idea? Or is just safe as like as upgrade like any other package? I prefer ultra stables release instead of latest higher package. 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. Thanks for all your tips, opinion and clarification! :) _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
