mergerfs - help!

I googled a bit this error (unable to parse branches) and this thing popped up.

root@pozz:~# sudo omv-showkey mergerfs

<mergerfs><pools/></mergerfs></services>

errors out in the last step, same as in error log

Ok, I did that. No output in the console and no pools in the mergerfs gui appear.

Should I check something?

Yes, the folder is populated, but the mergerfs doesn't show in the gui.

I checked with filezilla, all files are inside.

so to be clear, /mnt/test gets populated and has inside all my folders that you merged (Media and Media2)

It is not however present in the GUI, nor in /srv/mergerfs.

So even if I cannot use the gui, now the problem is solved?

My dear Aaron,

It's 2:13 here and in 4 hours I need to wake up.

Thank you very much for your support, you are really awesome.

If you do think of a solution that could work natively with the plugin in the OMV gui, please write it, if not, I will use it how you made it now.

What I would like to know though, in case I want to rename from /mnt/test to /mnt/pool

Have a good night/day

Thanks again

Yes, filesystems are 10TB (media) and 12 TB (media2). The hdd I mean. The files, I don't know for sure maybe 1 remux I have is over 100gb, but I am not sure.

Hi Aaron,

root@pozz:~# sudo mount -t fuse.mergerfs test:pool1 /mnt/pool -o branches=/srv/dev-disk-by-label-Media/Media:/srv/dev-disk-by-label-Media2/Media2,category.create=mfs,minfreespace=50G,fsname=test:pool1,defaults,allow_other,cache.files=off,use_ino

* ERROR: unable to parse 'branches' - test:pool1

* ERROR: mountpoint not set

Please note I used test:pool1 instead of test1:pool1 as the folder is /mnt/test (I thought that was a typo).

Should I run it with test1 how you instructed?

LE: also ran the command like yours, same error

root@pozz:~# sudo mount -t fuse.mergerfs test1:pool1 /mnt/pool -o branches=/srv/dev-disk-by-label-Media/Media:/srv/dev-disk-by-label-Media2/Media2,category.create=mfs,minfreespace=50G,fsname=test1:pool1,defaults,allow_other,cache.files=off,use_ino

* ERROR: unable to parse 'branches' - test1:pool1

* ERROR: mountpoint not set

Also I read in one thread that you recommand not using mergerfs in docker.

For me, this is the main purpose, since all my software is dockerized.

Mainly I'd want to migrate from

volumes:
    - /srv/dev-disk-by-label-Media/Media/Drone:/data/drone
    - /srv/dev-disk-by-label-Media2/Media2/Drone2:/data/drone2

to

- /srv/mergerfs/pool1/Media/Drone:/data/drone

Or I shouldn't use it at all in docker?

I also wouldn't use a mergerfs pool for your docker path.

Hi Aaron

root@pozz:~# dpkg -l | grep mergerfs

ii mergerfs 2.31.0-1 amd64 another FUSE union filesystem

ii openmediavault-mergerfs 6.3.3 all mergerfs plugin for openmediavault.

Zitat von ryecoaaron

We don't recommend using it for docker storage (path set in omv-extras) but it should be ok for docker volumes.

Thanks for the clarification
