NAME

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

SYNOPSIS

       mfsmetadirinfo [-f J|C|C x] [-o outputfile] [-a sum_name] metadata.mfs PATH [PATH...]

DESCRIPTION

       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

OUTPUT FIELDS

       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
