Ceph 17.2 Quincy Available as Preview and Ceph 15.2 Octopus soon to be EOL

[t.lamprecht]

Hi Community!

The recently released Ceph Quincy is now available as preview in the Proxmox repositories and is ready for upgrading or new installation.

Upgrades from Pacific to Quincy:
You can find the upgrade how to here: https://pve.proxmox.com/wiki/Ceph_Pacific_to_Quincy

New Installation of Quincy:
Use the updated ceph installation wizard available with the recently released pve-manager version 7.2-5.

We ran and tested the release since a few weeks internally and found no major issue, we'd still recommend that production setups avoid rushing the upgrade, but stay on Ceph Pacific (still supported until mid-2023) until we lift the preview status.

Our further plan is to lift the preview state and provided Quincy as fully supported Ceph version with the upcoming 17.2.1 stable version (expected to be released in the next days), that is once it successfully passed our QA and internal testing for the release itself and also for its Proxmox VE integration.

Please also remember that Ceph 15.2 Octopus is going to be end of life (EOL) after 2022-07 (end of next month), and you should upgrade any Ceph Octopus setups to Ceph Pacific rather sooner than later. See the respective upgrade how-to: https://pve.proxmox.com/wiki/Ceph_Octopus_to_Pacific

Used the directions linked in the OP to upgrade my test cluster from pacific to quincy.... Seems to be working fine/as expected so far.

Thanks for your really great work. I have question about CEPH Quincy. Softiron storage vendor which uses CEPH for commercial product, says that there are some problems with Quincy:

I'm interested if you encountered the same problems in your tests. Especially "performance regressions over time" mentoined in Softirons blog article.

Which problems do you mean in detail, please provide details, best a link to a bug report.

The linked blog does not talk about an issue/bug. Basically the guy just tells that they do not invest their resources to provide a well tested Quincy release ...

Installed Quincy on home/test cluster last night. Perfectly smooth install, no hiccups, no issues. Everything running smoothly. Perfect instructions as usual from the Proxmox team!
