In this article I will show you how to upgrade the Ceph version from Reef to Squid using Cephadm. A version upgrades is performed if the cluster has bugs and the bug has been fixed in the latest version, it can also be if there are new features in the latest version. I use Cephadm to upgrade the Ceph version automatically.
So, let's get started…
