mfsmetadirinfo8
Uses moosefs metadata to calculate precise directory information (similar to mfsdirinfo)
Usage
mfsmetadirinfo [{-f
J | C | C
x}]
[-o
outputfile]
[-a
sum_name]
metadata_file
PATH
[PATH ...]
Overview
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
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 |
