mfsmetadirinfo(8) This is part of MooseFS mfsmetadirinfo(8) NAME mfsmetadirinfo - uses MooseFS metadata to calculate precise directory in- formation (similar to mfsdirinfo) SYNOPSIS mfsmetadirinfo [-f J|C|C x] [-o outputfile] [-a sum_name] metadata_file 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 para- meter(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 charac- ter 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 in- formation for all supplied paths together (a sum), this calculation is indicated by sum_name in output data metadata_file path to metadata.mfs file 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 REPORTING BUGS Report bugs to <bugs@moosefs.com>.
