Hi Cephers, Why it is use journal with Filestore ? From my understand, it is used to prevent partial write. In my view ,it is needn't journal for Filestore as to the scenario for EC backend and for RGW object storage application. For EC backend, it just now only have write full and append write, truncate operations which already has rollback mechanism For RGW application, it only has append write. So, in my opinion, it should develop a type of filestore with no journal, and it writes data using aio which directly persisted data to disk. And the performance are also very good for large io. Am I right?
