Cannot mount Hetzner storage box for backups using SSHFS
-
@girish I mean, what can I say, other than a big THANK YOU. I'm sorry I missed the "/home" as being the root remote directory with sftp and you had to go through the bother of trying it out by yourself. It's weird they don't make it that explicit. I actually went through their docs too and went through the same steps as you did so I knew the set-up was working which is why I resorted to this forum and to you guys as a last resources (I promise I try not to ask you for help until I've exhausted my own resources ).
Now it's successfully switched to SSHFS my fingers are crossed I won't have any more backup issues (still the backup failures with CIFS are a mastery...got exactly the same set-up on two other instances and it never fails - all on the same storage box, same VPS provider, same OS, etc.).
-
@avatar1024 No worries, it was good to test it out with our mounting code. I found that Hetzner CIFS is SMBv1 (atleast per dmesg output) which is a thing of the past. This is why CIFS mounting is not working/not reliable.

Trying to connect a hetzner storagebox as Volume. I keep having the the error:
'Failed to mount (inactive): read: Connection reset by peer'I followed the guidline: https://docs.hetzner.com/robot/storage-box/backup-space-ssh-keys/#uploading-authorized_keys
- Hetzner Robot: SSH-Support enabled
- generated the key with oppenssh, uploaded the authorized_keys file.
- SFTP is working
Any idea?

@solarsimon are you able to manually mount this using a custom line in /etc/fstab or a sshfs mount command?
For reference in my Cloudron, which also uses Hetzner SSHFS for backups, the Cloudron generates the following systemd mount unit at
/etc/systemd/system/mnt-cloudronbackup.mount
:[Unit] Description=backup [Mount] What=u193526@u193526.your-storagebox.de:. Where=/mnt/cloudronbackup Options=allow_other,port=23,IdentityFile=/home/yellowtent/platformdata/sshfs/id_rsa_u193526.your-storagebox.de,StrictHostKeyChecking=no,reconnect Type=fuse.sshfs [Install] WantedBy=multi-user.target

using a custom line in /etc/fstab
From the basic knowlege i have, i tried doing that.
I followed some tutorials i found.
(https://ivan.reallusiondesign.com/mount-sshfs-volumes-in-fstab-with-ssh-key/ and https://www.bveml.net/de/news/hetzner-backup-space-inkrementelles-backup-mit-rsnapshot.html)- I added ssh key to /home/.ssh
- added fstap: sshfs#uxxxxx5@uxxxxxx5.your-storagebox.de:/home /mnt/backup/ fuse IdentityFile=/home/.ssh/id_rsa,uid=0,gid=0,users,idmap=user,noatime,allow_other,_netdev,reconnect,ro 0 0
- restarted the server
I find a folder mnt/backup/ without content. I placed some files in the storeagebox/home. No content in /media/
I'm a basic user coming from windows Trying my best^^
-
@solarsimon what you did seems to be correct from a quick glance. So looks like this is independent of Cloudron as such. Maybe the permissions of the SSH key file is too open? The permissions should be
-rw-------
so can you for a start try to runchmod 600 /home/.ssh/id_rsa
?Further are there any logs in the system logs while attempting to mount? Once you have the
/etc/fstab
line, you can usemount /mnt/backup
andumount /mnt/backup
without having to reboot the server. Logs may be found injournalctl --system

I made a clean installation of cloudron on a ubuntu hetzner server.
After that I could mount the storage box with the procedure I tried before without problems.So I dont know what was wrong. But now everything working fine.
Thanks -
@girish
I tried this exact same setup. I was able to connect to the storage via SFTP and my SSH key and I copied my private SSH key as instructed to Cloudron.When I now try to save the backup settings using SSHFS it keeps working and never finishes. The log says
Jan 14 11:40:33 box:shell addMount spawn: /usr/bin/sudo -S /home/yellowtent/box/src/scripts/addmount.sh [Unit]\nDescription=backup\n\nRequires=unbound.service\nAfter=unbound.service\nBefore=docker.service\n\n\n[Mount]\nWhat=uxxxxx@uxxxxx.your-storagebox.de:/\nWhere=/mnt/cloudronbackup\nOptions=allow_other,port=23,IdentityFile=/home/yellowtent/platformdata/sshfs/id_rsa_uxxxxx.your-storagebox.de,StrictHostKeyChecking=no,reconnect\nType=fuse.sshfs\n\n[Install]\nWantedBy=multi-user.target\n\n 10 Jan 14 11:40:44 box:shell addMount (stdout): Failed to mount Jan 14 11:40:44 box:shell addMount code: 3, signal: null Jan 14 11:42:04 box:shell removeMount spawn: /usr/bin/sudo -S /home/yellowtent/box/src/scripts/rmmount.sh /mnt/cloudronbackup
Not sure what else I can try.
Edit: magically and waiting one night it works now.

I'm sorry to reopen this, but I've been trying to connect Hetzner volumes and I'm stuck with the key-gen command at the server. I'm pretty sure there's something I'm understanding poorly, but I would like to connect the Volumes with my Cloudron instance, but there's no way I can run key-gen on the Volumes via SSH to get them connected.

Hetzner Volumes
Hetzner Cloud Volumes are a very different product to their Storage Boxes.
I don't think you can access them in the same way.
You can definitely use them as a Cloudron Volume though. I think you just have to mount them on your VPS server using fstab first.

Oh I'm sorry, just to clarify, I'm trying to use Storage Boxes as Cloudron Volume.

Ah, OK. I've got that set-up but I've only ever used CIFS and not SSHFS so not sure what you have to do myself sorry.

It says as much that it is a restricted shell. Not sure how to generate keys though, maybe a question for hetzner support.

Ah, but Girish gave instructions above in this very thread!
As @robi said if you don't have ssh-keygen installed, install it.

For me. It's silly. All the guide is out of date. With new created storage box, there isn't sub dir and ssh pub key is not yet allowed in storage box and storage box's pub isn't in my pc known_hosts, I have to add my pub key to storage and run sshfs command once time to get pub key of storage box. So because of new user without subdirectory, the "remote dir path" after colon should be RELATIVE path or empty "" in this case not "/". uxxxxxx@uxxxxxx.your-storagebox.de: /mnt/local/mount/path -o port=23,IdentifyFile=/home/username/.ssh/id_rsa ....

Hey folks
I recently struggled a bit with those steps as well, but it was because I had set a passphrase for my SSH keys at creation time and Cloudron does not prompt for that anywhere.
Is that in the plans for the future @girish ?Thanks !
-
@SansGuidon how would automatic mounting on boot work if the ssh key had a passphrase? If you put the password in clear text in a config file, it's probably more insecure than having no password at all (especially if you reuse passwords or a part of it...).
