It is clear because everyone agrees on the definition. And it is self explanatory because it's an art term for a well defined concept which forms one of the building blocks of the nomenclature used in clustering. Even if you're not familiar with clustering terminology, the definitions are easy to find via search engines. If you want to find useful quibbles, the term synchronously is wrong: DRBD is capable of both synchronous and asynchronous replication.
