Raspberry ISO mount via sshfs fails

I hope someone can help me with my problem.

Background: I want to mount very big ISOs to my raspberry via sftp. If I try to mount the iso from a local folder, for example Downloads\2005-2010.iso it works perfect. But if I try to mount the ISO from a mounted sshfs folder, it fails. I also tryed to change the permission to 777 (only for testing) to the mounted ftp folder, but no success.

I using "sshfs" to mount my ftp webhosting folder. (Works perfect)

The Output is different to the following statements:

  1. Statement

sudo mount /home/pi/isomount/2005-2010.iso /home/pi/medien/2005-2010/

1.1 Output

mount: /home/pi/medien/2005-2010: cannot mount /home/pi/isomount/2005-2010.iso read-only.

  1. Statement

sudo mount -o loop /home/pi/isomount/2005-2010.iso /home/pi/medien/2005-2010/

2.1 Output

mount: /home/pi/medien/2005-2010/: failed to setup loop device for /home/pi/isomount/2005-2010.iso.

Any idears what I can do to mount this .iso?

Solution

  • For me, this worked :

    sudo bash
# Now in root
mkdir /tmp/iso
mount /home/pi/isomount/2005-2010.iso /tmp/iso
