Hello Zac,
If possible also include the installation guide.
Regards

The Upstream Documentation Team is writing a
Beginner's Guide. If you're
reading this email, then you are invited to contribute to it.
I have a firm idea of what I want the Beginner's Guide to contain, but it
is important to me to consult the Ceph community during the early stages of
the composition of the Beginner's Guide, to make sure that we create a
Beginner's Guide that is useful.
The first section of the Beginner's Guide will be a brief overview of the
components of a Ceph cluster. This section will be brief enough to be read
in just a couple of minutes.
The second section of the Beginner's Guide will be a set of reference
architectures. This section will describe the differences between the
different kinds of clusters. For example, a CephFS cluster requires
Monitors, Managers, OSDs, and also Metadata Servers. An object storage
cluster requires Monitors, Managers, OSDs, and a RADOS Gateway. The second
section of the Beginner's Guide will describe the various kinds of storage
clusters and the pieces that each of the kinds requires. After reading this
section, a beginner will know for example which kind of cluster requires a
metadata server (it's a CephFS cluster).
I am considering writing a third section of the Beginner's Guide that
addresses early misconceptions about Ceph. This section would consist of
things that people wish they had known when they started using Ceph. The
User+Dev Monthly Meetup of November 2023 generated a beefy list of these
things, and here are some of them: different storage types (block, file,
object) are all built on RADOS, but they don't interact with each
other--you can't treat your S3 bucket the way you treat a CephFS directory;
there is a difference between a RADOS object and an S3 object. This section
would also answer some Ceph-beginner questions: just what is the CRUSH map
and what does it do?; which components of a Ceph cluster can run in VMs and
which must run on bare metal?; what is the difference between consumer
grade hardware and enterprise grade hardware?
I expect to have finished writing the Beginner's Guide by Cephalocon 2024.
Please tell me if there is something that you'd like to see in a Ceph
Beginner's Guide that I haven't mentioned.
