I am updating the Ceph documentation. Included in this email is a proposed change to the documentation and a request for information pertaining to that proposed change.

Documentation Link: http://docs.ceph.com/docs/master/start/os-recommendations/
Proposed Change: I'd like to update the list of OS recommendations, and to get a list of kernel versions that are supported. If this is not possible, I would like to publish a list of OSes and kernels on which people in the community have successfully tested Ceph.
I think the way to approach this is a blanket statement like:
Generally speaking, Ceph should work on any modern Linux distribution. In practice, we build packages for and test on a select set of common distributions.
Starting with Octopus, we recommend deployments consume Ceph via a container image instead of packages. The container itself is based on CentOS 8. The container is generally consumed by either Rook.io or the ceph-daemon tool. In the later case, the OS requirements are relaxed, ...
Specifically, we build packages for:
...
We test on:
...
Something along those lines?
Zac's Request: Reply to this email if you know of OSes or kernels th Ceph has been successfully tested on, and if those OSes or kernels are not already in the list.
By the time of octopus release, I belive this will be:
Build - CentOS 8 (x86_64) - Ubuntu 18.04 (x86_64) - Ubuntu 18.04 (aarch64) (I think?)
Test - centos 7.6 (containerized ceph only) - centos 8.0 - ubuntu 18.04
We need to pin this down pretty soon. Much of this is piled up behind the py3 conversion, which is oh-so-close...
Could we also get an updated Fedora-based recommendation? It's kind of depressing to see Fedora 22 still mentioned on the website. I personally run Ceph on Fedora rather than CentOS, and pretty much all the guidelines for CentOS 8 would apply to a recent Fedora version. -- 真実はいつも一つ！/ Always, there's only one truth!
