Just download the package and install them wherever.

It's just a standard tarball with statically compiled binaries. I build them every release.

I came up with

cd /tmp

wget https://github.com/trapexit/mergerfs/releases/download/2.36.0/mergerfs-static-linux_amd64.tar.gz

mv /tmp/usr/local/bin/mergerfs /bin
rm -r /tmp/usr/

I installed your plugin and tried a basic configuration.

I have 9 btrfs-formatted SSDs mounted and when I run the mergerfs command to create the "pool", it appears to run and exit without error (code 0)... however the new mountpoint does not show up in "df -h", nor can I "cd" to the directory or "ls" it....  when I run umount, it also exits without error, like it correctly unmounted the new mountpoint, and if I re-run umount, it will error saying "not mounted" (as it should).

So it appears as though something is either wrong with the options I am using to create the new mount, or there is a bug somewhere.

I also tried using fstab and also directly on the command line, both with the same effect.

 

# Disk mounts

 

/dev/sdm1             1.5T  1.5T   30G  99% /mnt/netapp/disk1

/dev/sdu1             3.5T  3.8M  3.5T   1% /mnt/netapp/parity1     (planning to use this with snapraid, once mergerfs is working)

 

# The mergerfs command I used:

 

root@UNAS:/# mergerfs -o allow_other,use_ino,cache.files=partial,dropcacheonclose=true,category.create=mfs,minfreespace=10G,fsname=mergerfs /mnt/appdata/disk* /pool/
root@UNAS:/# ls /pool  
/bin/ls: cannot access '/pool': No such file or directory
root@UNAS:/# umount /pool
root@UNAS:/#

 

Any help you can provide would be greatly appreciated.

 

Thanks!

Is this on UNRAID?  You have a weird mount setup for that - how do you mount these /netapp/ mounts?

Also, are you sure your appdata is at /mnt/appdata ? It's usually on /mnt/user/appdata, /mnt/disk[number]/appdata?!

Please check your paths again and possibly put 2>&1 behind your mergerFS commands so you'll also see any errors from stderr.
