I have seen the basic idea of ufs\aufs cache_dir which contains the DB that holds the dynamic data and the cache_dir files structure(TLV etc).
Before I am even trying to understand rock basic structure I am looking for a tiny briefing about it. 1. how is the rock organized compared to ufs? 2. what is the rock file structure?binary I assume..? 3. assuming we want to *purge* from the rock cache_dir an object when the server is offline what would be the pseudo code to do that? If you can start with something from the above it would be good and then we can try to go on. Once I will have couple hints I will try to read some of the code to make sure I understood it right. Thanks, Eliezer
