Octopus on Ubuntu 20.04.6 LTS with kernel 5
Hi, In octopus documentation we can see kernel 4 as recommended, however we've changed our test cluster yesterday from centos 7 / 8 to Ubuntu 20.04.6 LTS with kernel 5.4.0-148 and seems working, I just want to make sure before I move to prod there isn't any caveats.

I can answer my question, even in the official ubuntu repo they are using by default the octopus version so for sure it works with kernel 5. https://packages.ubuntu.com/focal/allpackages -----Original Message----- From: Szabo, Istvan (Agoda) <Istvan.Szabo@agoda.com> Sent: Thursday, May 11, 2023 11:20 AM To: Ceph Users <ceph-users@ceph.io> Subject: [ceph-users] Octopus on Ubuntu 20.04.6 LTS with kernel 5 Hi, In octopus documentation we can see kernel 4 as recommended, however we've changed our test cluster yesterday from centos 7 / 8 to Ubuntu 20.04.6 LTS with kernel 5.4.0-148 and seems working, I just want to make sure before I move to prod there isn't any caveats.

As a KRDB client, I believe that 5.4 also introduces better support for RBD features including fast-diff

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. Thanks, Ilya
Hi, Pacific and quincy still supports barematel deloyed setup?
