# mergerfs-tools

Optional tools to help manage data in a mergerfs pool.

## INSTALL

All of these suplimental tools are self contained Python3 apps. Make sure you have Python 3 installed and either run `make install` or copy the file to `/usr/local/bin` or wherever you keep your binarys and make it executable (chmod +x).

## TOOLS
### mergerfs.ctl

A wrapper around the mergerfs xattr interface.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.ctl)

```
$ mergerfs.ctl -h
usage: mergerfs.ctl [-h] [-m MOUNT] {add,remove,list,get,set,info} ...

positional arguments:
{add,remove,list,get,set,info}

optional arguments:
-h, --help show this help message and exit
-m MOUNT, --mount MOUNT
mergerfs mount to act on
$ mergerfs.ctl info
- mount: /storage
version: 2.14.0
pid: 1234
srcmounts:
- /mnt/drive0
- /mnt/drive1
$ mergerfs.ctl -m /storage add path /mnt/drive2
$ mergerfs.ctl info
- mount: /storage
version: 2.14.0
pid: 1234
srcmounts:
- /mnt/drive0
- /mnt/drive1
- /mnt/drive2
```

### mergerfs.fsck

Audits permissions and ownership of files and directories in a mergerfs mount and allows for manual and automatic fixing of them.

It's possible that files or directories can be duplicated across multiple drives and that their metadata become out of sync. Permissions, ownership, etc. This can cause some strange behavior depending on the mergerfs policies used. This tool helps find and fix those inconsistancies.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.fsck)

```
$ mergerfs.fsck -h
usage: mergerfs.fsck [-h] [-v] [-s] [-f {manual,newest,nonroot}] dir

audit a mergerfs mount for inconsistencies

positional arguments:
dir starting directory

optional arguments:
-h, --help show this help message and exit
-v, --verbose print details of audit item
-s, --size only consider if the size is the same
-f {manual,newest,nonroot}, --fix {manual,newest,nonroot}
fix policy
$ mergerfs.fsck -v -f manual /path/to/dir
```

### mergerfs.dup

Duplicates files & directories across branches in a pool. The file selected for duplication is picked by the `dup` option. Files will be copied to drives with the most free space. Deleted from others if `prune` is enabled.

See usage for more. Run as `root`. Requires `rsync` to be installed.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.dup)

```
usage: mergerfs.dup []

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.dedup

Finds and removes duplicate files across mergerfs pool's branches. Use the
`ignore`, `dedup`, and `strict` options to target specific use cases.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.dedup)

```
usage: mergerfs.dedup []

Remove duplicate files across branches of a mergerfs pool. Provides
multiple algos for determining which file to keep and what to skip.

positional arguments:
dir Starting directory

optional arguments:
-v, --verbose Once to print `rm` commands
Twice for status info
Three for file info
-i, --ignore= Ignore files if... (default: none)
* same-size : have the same size
* different-size : have different sizes
* same-time : have the same mtime
* different-time : have different mtimes
* same-hash : have the same md5sum
* different-hash : have different md5sums
-d, --dedup= What file to *keep* (default: newest)
* manual : ask user
* oldest : file with smallest mtime
* newest : file with largest mtime
* largest : file with largest size
* smallest : file with smallest size
* mostfreespace : file on drive with most free space
-s, --strict Skip dedup if all files have same value.
Only applies to oldest, newest, largest, smallest.
-e, --execute Will not perform file removal without this.
-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.dedup /path/to/dir
# Total savings: 10.0GB

# mergerfs.dedup -e -d newest /path/to/dir
mergerfs.dedup -v -d newest /media/tmp/test
rm -vf /mnt/drive0/test/foo
rm -vf /mnt/drive1/test/foo
rm -vf /mnt/drive2/test/foo
rm -vf /mnt/drive3/test/foo
# Total savings: 10.0B
```

### mergerfs.balance

Will move files from the most filled drive (percentage wise) to the least filled drive. Will do so till the most and least filled drives come within a user defined percentage range (defaults to 2%).

Run as `root`. Requires `rsync` to be installed.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.balance)

```
usage: mergerfs.balance [-h] [-p PERCENTAGE] [-i INCLUDE] [-e EXCLUDE]
[-I INCLUDEPATH] [-E EXCLUDEPATH] [-s EXCLUDELT]
[-S EXCLUDEGT]
dir

balance files on a mergerfs mount based on percentage drive filled

positional arguments:
dir starting directory

optional arguments:
-h, --help show this help message and exit
-p PERCENTAGE percentage range of freespace (default 2.0)
-i INCLUDE, --include INCLUDE
fnmatch compatible file filter (can use multiple
times)
-e EXCLUDE, --exclude EXCLUDE
fnmatch compatible file filter (can use multiple
times)
-I INCLUDEPATH, --include-path INCLUDEPATH
fnmatch compatible path filter (can use multiple
times)
-E EXCLUDEPATH, --exclude-path EXCLUDEPATH
fnmatch compatible path filter (can use multiple
times)
-s EXCLUDELT exclude files smaller than [KMGT] bytes
-S EXCLUDEGT exclude files larger than [KMGT] bytes

# mergerfs.balance /media
from: /mnt/drive1/foo/bar
to: /mnt/drive2/foo/bar
rsync ...
```

### mergerfs.consolidate

Consolidate **files** in a **single** mergerfs directory onto a **single** drive, recursively. This does **NOT** move all files at and below that directory to 1 drive. If you want to move data between drives simply use normal rsync or similar. This tool is only useful in niche usecases where the person wants to colocate files of their TV, music, etc. files onto a single drive *after the fact.* If you really wanted that you should probably use path preservation. For most people there is only downsides to using path preservation or colocating files.

Run as `root`. Requires `rsync` to be installed.

[Download latest](https://raw.githubusercontent.com/trapexit/mergerfs-tools/master/src/mergerfs.consolidate)

```
usage: mergerfs.consolidate []

positional arguments:
dir starting directory

optional arguments:
-m, --max-files= Skip directories with more than N files.
(default: 256)
-M, --max-size= Skip directories with files adding up to more
than N. (default: 16G)
-I, --include-path= fnmatch compatible path include filter.
Can be used multiple times.
-E, --exclude-path= fnmatch compatible path exclude filter.
Can be used multiple times.
-e, --execute Execute `rsync` commands as well as print them.
-h, --help Print this help.
