Hi there,

Thank you for your feedback. This is too far to travel for me 🙂

The book looks good, maybe it's a little outdated.
I got the point, that it is good to come around with clear questions to you all, here on the list.

Best regards,

Alexander

I'm partial to this one

https://www.amazon.com/s?k=learning+ceph+second+edition&crid=1NILUH0R7APSL

The basics, like what are the components, what are OSDs and PGs, rough ideas of sizing, etc. are still quite valid, but a lot has changed since it came out.  Like widespread adoption of the PG autoscaler and cephadm, automatic stepping of pgp_num.  I *think* it covers the balancer but it's evolved since then for sure.

There's a new user workshop @ Cephalocon next week.  If you aren't yet attending, that would be a really good way to dive in, and you'd find scores of us who love talking Ceph all day and all night.

There are some published books out there written by community members that can be useful. Some talks on youtube as well that can be useful for understanding core concepts. 

What kind of things are you confused about and maybe we can help here directly. Usually the out of the box CRUSH rule is default to host so there is that.

Hi everybody,

I'm new to ceph. I'm testing 4 proxmox ceph nodes.

I researched a lot on CRUSH rules and I build a rbd pool for use with my test-vms.

I'm reading a lot in the official docs under docs.ceph.com (Protected link to ceph.com). But I still have a lot of white space on my personal knowledge map.

Are there any other recommendations for getting a full / deeper understanding of ceph? books?

Best regards,
Alexander
