Why are you pointing dup tool at something other than mergerfs mount?

[rementis]

Maybe I don't understand. I want everything in /media/media12 to be duplicated. /media/media12 is one of the mounts included in /plex_media

[trapexit]

The tool is for duplicating files. Not mounts. You point it at mergerfs mounts and configure it to set the number of files to have among the branches.

[rementis]

Can you give me an example of command line? Is this for duplicating the entire mergerfs filesystem?

[trapexit]

usage: mergerfs.dup [<options>] <dir>

Duplicate files & directories across multiple drives in a pool.
Will print out commands for inspection and out of band use.

positional arguments:
  dir                    starting directory

optional arguments:
  -c, --count=           Number of copies to create. (default: 2)
  -d, --dup=             Which file (if more than one exists) to choose to
                         duplicate. Each one falls back to `mergerfs` if
                         all files have the same value. (default: newest)
                         * newest   : file with largest mtime
                         * oldest   : file with smallest mtime
                         * smallest : file with smallest size
                         * largest  : file with largest size
                         * mergerfs : file chosen by mergerfs' getattr
  -p, --prune            Remove files above `count`. Without this enabled
                         it will update all existing files.
  -e, --execute          Execute `rsync` and `rm` commands. Not just
                         print them.
  -I, --include=         fnmatch compatible filter to include files.
                         Can be used multiple times.
  -E, --exclude=         fnmatch compatible filter to exclude files.
                         Can be used multiple times.

mergerfs.dup /plex_media/some/path

Oooooooo! Will try, thanks!
