curl https://rclone.org/install.sh | sudo bash
rclone config

after that, the config will resides in

~/.config/rclone/rclone.conf

and will look something like this (I enabled encryption too, because why not :

[backup]
type = sftp
host = u123456-sub1.your-storagebox.de
user = u123456-sub1
port = 23
pass = hashed_pwd
md5sum_command = md5 -r
sha1sum_command = sha1 -r
shell_type = unix
idle_timeout = 0

[backupcrypt]
type = crypt
remote = backup:backup

mounting:

mkdir /mnt/backup
chown -R yellowtent:yellowtent /mnt/backup
rclone mount backupcrypt: /mnt/backup \
    --crypt-password "verylonghashedpwd" \
    --crypt-password2 "evenlongerhashedpwd" \
    --vfs-cache-mode writes --daemon --transfers 3 --checkers 6 --allow-other

The last bit was the important one, without it mounting wasn't possible. You should now be able to mount the rclone thing as a volume. For whatever reason it shows the red dot, I'm guessing that's because of the fs. However, I haven't had an issue with that in months. Currently I'm mounting it manually on every machine reboot, but there are ways to mount it automatically.

/mnt# node -e "console.log(fs.realpathSync('/mnt/media'))"
/mnt/media

Your command doesn't fail, but doesn't give any output either.

My bad... Can you try like this:

root@my:/mnt# node -e "console.log(fs.realpathSync('/mnt/folder'))"
/mnt/folder

/mnt# ls -la
total 12
drwxr-xr-x  4 root root 4096 Jun  9 09:21 .
drwxr-xr-x 23 root root 4096 Dec 17 11:10 ..
drwxr-xr-x  1 root root    0 Jun  9 09:22 media
drwxr-xr-x  2 root root 4096 Dec 17 11:31 volumes

Your command doesn't fail, but doesn't give any output either.

Can you try node -e "fs.realpathSync('/the/path')" ? This function is failing or returning something other than the path you are adding for some reason.

When trying to I am trying to add the /mnt/folder to Cloudron as a filesystem volume type, I am getting this error: hostPath must be a realpath without symlinks

Just tested this and this works fine here. Is /mnt/folder a symlink? I have a fstab line to mount a sshfs into /mnt/folder . And then I just added Filesystem mount type in Volumes view.

or direct block device

https://linbit.com/drbd/ is the gold standard.

Great workaround! I will try it.

Solving it at the hypervisor level is not any better than directly on the cloudron vm. There is no way to share a folder to a vm. Only nfs, cifs, sshfs or direct block device.

The reason is that our phones are growing, and at current I need to sync 5x family members phones at 1tb. Not insane anounts of course, but way beyond the m2.ssd cloudron is running on.

Also, I'm doing this with Nextcloud for the exact same reason - I want to manage my pictures. I'm trying the "Memories" plugin in Nextcloud which has prettty good reviews. I'll probably move on to Immich next for testing.
