    Description

      Add replication for specified non-directory MDT objects (typically regular files)

      • New "lfs setdirstripe" option to specify MDT file object replication
      • Inherit LMR attribute for files from parent by default
      • Handled like non-replicated remote objects with local agent if parent is LMR && child is non-LMR
        • since agent inode is allocated anyway, space of replication is already used
        • need to keep file layout, xattrs, timestamps, etc. uptodate on replica
      • mark agent/replica files to identify/skip by MDT scanning tools

      Leverage/enhance LMR1 tools for conversion between LMR file(s) and non-LMR file(s).

      Enhance LFSCK to verify and repair LMR files (resync attributes as needed).
