How to upgrade Hyper Converged Ceph Cluster: Reef to Squid

Описание: The exact proxmox wiki documentation I used - https://pve.proxmox.com/wiki/Ceph_Ree...

In this video, I'll walk you through the entire process of upgrading your Ceph cluster from version Reef 18.2.7 to Squid 19.2.2 within a Proxmox Virtual Environment (PVE) Cluster. This is a crucial step for anyone managing a hyper-converged infrastructure (HCI), as the latest Ceph version offers significant performance improvements, enhanced stability, and new features. I'll cover everything you need to know, from upgrading on each node within a cluster to restarting the services for proper operations to verifying the upgrade on both Linux CLI and Proxmox UI.
