Is it possible to test distrubuted file systems like HDFS using the existed models? #32

Well, I want to test the linearizability of my own distributed file system, which is similar to HDFS. And I have seen there are some useful models already such as cas-register and multi-register, but I don't know how to apply these models to the file systems, which is a little different from a key-value store. For example, in a file system, writing/reading is at a certain offset while the key-value store is writing/reading the key's whole value. I want to ask if there are any possibilities that I can use the existed models here or I have to write my own models? Since I'm not an English native speaker, my sentences or words above may not accurate, sorry in advance and looking forward to your reply!

Yeah, I think you'd need to build a different kind of model that represents the sorts of operations you'd like to perform on your filesystem. I'm not sure what that would look like!
