I need to find out what MDS data I can access directly from an application, via IO system calls or Lustre commands assuming I am the owner of the file.
Or is any access to MDS data indirect, e.g. stat() and does that go just to the MDS, or to the file as well? I have a customer who has a large number of 1K files, that I suspect are simply pointers to something a crude MDS in other words. So on one hand this is a perfect app for Lustre, just load the real files into Lustre and the Lustre MDS points to the actual files! But if the small files point to other objects that are not files, like a physical file cabinet, are there system calls or commands that can be used to load and read data into the Lustre MDS itself? This probably isn¹t a good app for Lustre, and am asking in part to learn.
