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.

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.
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
