The general advice[1] on this is not to try and use a 3.x kernel with CephFS. The only exception is if your distro provider is doing special backports (latest RHEL releases have CephFS backports). This causes some confusion, because a number of distros that have shipped "stable" kernels with older, known unstable CephFS code. If you're building your own kernels then you definitely want to be on a recent 4.x John 1. https://urldefense.proofpoint.com/v2/url?u=http-3A__docs.ceph.com_docs_master_cephfs_best-2Dpractices_-23which-2Dkernel-2Dversion&d=DwICAg&c=5m9CfXHY6NXqkS7nN5n23w&r=5r9bhr1JAPRaUcJcU-FfGg&m=1d2qC0CtsbiZASGIWepKvVV0aMaJAXZZmg2_NDncscw&s=nAbQCNqk5k58F3w1fk-APMYb49ODP3WlGtdkQNjwU4Q&e= > The reason I ask is that I have been trying to get some clients running > Linux kernel 3.16 (the current long term stable Linux kernel) and so far > I have run into two serious bugs that, it turns out, were found and fixed > years ago in more current mainline kernels. > > In both cases, I emailed Ben Hutchings, the apparent maintainer of 3.16, > asking if the fixes could be added to 3.16, but was met with silence.
