Hello list, I'd like to implement sliding window and hight water mark deletion on a lustre filesystem. For that I need information from all files. A first idea was to recursivly traverse the file tree and to a `stat filename` for every file to collect the meta data.
Now since in lustre the meta data is stored on the mds, I though that maybe there is a more efficient way of collecting the information. So the question is: is there a way that I could query the mds for the information that stat would give me(I need access, modify, creation time plus the file size). And if so, can someone guess the performance increase of quering the mds directly over using `stat` ? We are using lustre 1.6.something.
