Why a configuration option is in a registry key and not in the interface?

My job at Veeam is the first time in my IT career working in a software company, and I’ve learned a ton of things about software development. Not as a developer myself, since I don’t have any code writing skill (I wouldn’t call my low scripting capabilities “coding”), but partecipating to internal discussions about development has been so far an interesting experience. One of the most fascinating things I’ve learned is UX (User Experience) development, in particular around the User Interface.

My adventures with Ceph Storage. Part 10: Upgrade the cluster

As any existing software, Ceph is subject to minor and major releases. My entire series of posts has been realized using version Giant (0.87), but by the time I completed the series, Hammer (0.94) was released. Note that Ceph, as other linux softwares, uses a major release naming scheme based on the letter of the alphabet, so Giant is the 7th major release. Ceph releases both minor and major versions of the software, so it’s important to know how to upgrade it.
