Juan: You may have hit upon another problem that we've encountered where the splitting of directories goes into a race condition. Try this:
1. In your orangefs-server.conf file, set DistrDirServersInitial 1 and DistrDirServersMax 1 in your multi-server configuration installation. 2. Delete your data and metadata areas and recreate. Start your servers. 3. Run your tests. See if this helps! NOTE: We are working on a fix for this problem right now but don't have a working solution just yet.
