Just thought I'd share a quick tip on howto mount a iso -image on your readynas.
Let's assume that you've uploaded a arbitrary cdrom-backup image called image.iso.
Loggin in via ssh and trying to mount it with the usual:
mkdir /mnt/loop mount -o loop image.iso /mnt/loop
Will get you return:
mount: unknown filesystem type 'iso9660'
This is because the kernel module needed for interpreting an iso -image isn't included in the ReadyNas -distro.
In order to solve this one could spend time with downloading the kernel source/ headers and compile and link up the necessary modules or do it a bit more the easy way. Let's use FUSE instead, fuse is a toolkit for filesystem-userspace-utilities. Enabling non-root users, i.e. users that aren't allowed by the OS to perform kernel tasks.
To install fuse and forthcoming necessary tools, you'll simple just type:
Chances are the fuse-utils and libfuse-dev are already installed per-default on your system, but the above install -line won't hurt them. 😄
Then, to actually be able to mount an image in userspace, we need to install the fuseiso application. It's probably available in some shaky repo out there, but since it's a very small app, we might as well build it locally.
Extract it, change directory, build and install it
cd fuseiso-20070708 ./configure ; make install
All done!
Let's mount it:
fuseiso image.iso /mnt/loop
That's it, your image is now mounted under /mnt/loop, and if you like you can share it by instead mounting the image within an existing share. The media share for example
fuseiso image.iso /c/media/loop
Do make sure that you have the proper permissions on the share in order to make it work. Remeber, it's userspace, so access permissions doesn't apply in the normal way. Depending on your setup, you might wanna switch to the user "nobody" i.e.
May I suggest using checkinstall to get a deb package from the compilation process and then being able to manage the package via the package manager. While this might not be that important in this particular situation, it can greatly help when fullfilling dependencies by manually compiling stuff.
