mfsmetadirinfo(8)	    This is part of MooseFS	     mfsmetadirinfo(8)

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

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

       mfsmetadirinfo  is  a tool that can be used to calculate	precise	direc-
       tory 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	direc-
       tory(ies) specified by PATH parameter(s)	- relative  in	mfs  instance.
       Default	output	is  human-readable  plain text,	JSON or	CSV can	be se-
       lected using 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 sepa-
	      rator 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	calcu-
	      lation is	indicated by sum_name in output	data

       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
