   3    usage: [--print] <mapfilename>
   4      --create-from-conf      creates an osd map with default configurations
   5      --createsimple <numosd> [--clobber] [--pg-bits <bitsperosd>] [--pgp-bits <bits>] creates a relatively generic OSD map with <numosd> devices
   6      --pgp-bits <bits>       pgp_num map attribute will be shifted by <bits>
   7      --pg-bits <bits>        pg_num map attribute will be shifted by <bits>
   8      --clobber               allows osdmaptool to overwrite <mapfilename> if it already exists
   9      --export-crush <file>   write osdmap's crush map to <file>
  10      --import-crush <file>   replace osdmap's crush map with <file>
  11      --health                dump health checks
  12      --test-map-pgs [--pool <poolid>] [--pg_num <pg_num>] [--range-first <first> --range-last <last>] map all pgs
  13      --test-map-pgs-dump [--pool <poolid>] [--range-first <first> --range-last <last>] map all pgs
  14      --test-map-pgs-dump-all [--pool <poolid>] [--range-first <first> --range-last <last>] map all pgs to osds
  15      --mark-up-in            mark osds up and in (but do not persist)
  16      --mark-out <osdid>      mark an osd as out (but do not persist)
  17      --with-default-pool     include default pool when creating map
  18      --clear-temp            clear pg_temp and primary_temp
  19      --test-random           do random placements
  20      --test-map-pg <pgid>    map a pgid to osds
  21      --test-map-object <objectname> [--pool <poolid>] map an object to osds
  22      --upmap-cleanup <file>  clean up pg_upmap[_items] entries, writing
  23                              commands to <file> [default: - for stdout]
  24      --upmap <file>          calculate pg upmap entries to balance pg layout
  25                              writing commands to <file> [default: - for stdout]
  26      --upmap-max <max-count> set max upmap entries to calculate [default: 10]
  27      --upmap-deviation <max-deviation>
  28                              max deviation from target [default: 5]
  29      --upmap-pool <poolname> restrict upmap balancing to 1 or more pools
  30      --upmap-save            write modified OSDMap with upmap changes
  31      --upmap-active          Act like an active balancer, keep applying changes until balanced
  32      --dump <format>         displays the map in plain text when <format> is 'plain', 'json' if specified format is not supported
  33      --tree                  displays a tree of the map
  34      --test-crush [--range-first <first> --range-last <last>] map pgs to acting osds
