Hi Istvan, Note that on https://docs.ceph.com/en/octopus/start/os-recommendations/ it starts with: > If you are using the kernel client to map RBD block devices or mount CephFS, > the general advice is to use a “stable” or “longterm maintenance” kernel > series provided by either http://kernel.org or your Linux distribution on any > client hosts. The recommendation for 4.x kernels follows that just as a precaution against folks opting to stick to something older. If your distribution provides 5.x or 6.x stable kernels, by all means use them! A word of caution though: Octopus was EOLed last year. Please consider upgrading your cluster to a supported release -- preferably Quincy since Pacific is scheduled to go EOL sometime this year too.
