mfsmetadirinfo  is  a  tool that can be used to calculate precise directory information such as number of
       inodes, number of chunks, total length of all files, size, real size etc.  Output  can  be  generated  as
       plain  text,  CSV or JSON.  Data for calculations is read from indicated metadata.mfs mfs master metadata
       file and is calculated for directory(ies) specified by PATH parameter(s)  -  relative  in  mfs  instance.
       Default output is human-readable plain text, JSON or CSV can be selected using options.

       Options:

       -f     switch  output  format  to JSON (J) or CSV (C); for CSV, if only C is specified, default separator
              will be used (comma), if second character is  specified,  this  character  will  be  used  as  the
              separator in CSV data

       -o     write output to outputfile instead of stdout

       -a     optional parameter that indicates the tool should calculate the information for all supplied paths
              together (a sum), this calculation is indicated by sum_name in output data

       metadata_file
              path to metadata.mfs file

       mfsmetadirinfo - uses MooseFS metadata to calculate precise directory information (similar to mfsdirinfo)

       For each PATH and, if defined, for sum_name, following information will be indicated:

       inodes    number of all unique inodes (file system objects)

       files     number of all unique files

       dirs      number of all unique directories

       chunks    number of all unique chunks

       kchunks   number of all unique chunks using KEEP policy

       achunks   number of all unique chunks using ARCH policy

       length    total length of all unique files

       size      total size of all unique chunks

       rsize     total real size of all unique chunks (number of copies taken into account)

       ksize     hypothetical real size of all unique chunks if all were using KEEP policy

       asize     hypothetical real size of all unique chunks if all were using ARCH policy
