to mount an image I use this commands:
modprobe nbd
imagemount -d /dev/nbd0 -f /media/Backup/image1.img -r -m /media/MountedImage -t ext4
It works fine.
Now I want to switch off the mounted image1 and to mount another image2. How should I proceed?
Additionally I tried to delete nbd before this, and then to proceed as described at first. But this is refused:
modprobe nbd -r => modprobe: FATAL: Module nbd is in use.
Once having used nbd0, only rebooting the system makes it possible to mount another image ... a little bit unpractical.
What can I do to switch off or reuse nbd0 and to mount different images on the fly?
Perhaps a silly question but I'm still a linux beginner just having migrated from XP ...

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
You probably need to kill the imagemount process (kill -HUP $(cat /var/run/imagemount.nbd0.pid) in most instances) after unmounting the first image.
Let me know if that does not work.

Thank you for hint - it works!
However I used command 'sudo kill $(cat /var/run/imagemount.nbd1.pid)'
Differences:
- no options -HUP because I didn't understand them due to missing explanation in man page
- '/var/run/imagemount.nbd0.pid' didn't exist

Hi,
to mount an image I use this commands:

I tried:
umount /media/MountedImage
imagemount -d /dev/nbd0 -f /media/Backup/image2.img -r -m /media/MountedImage -t ext4
Result:
/media/MountedImage is cleared
imagemont ...: nothing happens, /media/MountedImage remains empty.

kill -HUP <pid> is the same as kill -s SIGHUP <pid> or kill -s 1 <pid> - the first form is built in to bash.</pid></pid></pid>
Subsequently noticed:
Isn‘t there a proper regular command to stop nbd instead of this brute force ‚kill'-method?
With ‚rmmod nbd‘ it‘s the same as with ‚modprobe nbd -r‘: command is refused with error message ‚Module nbd is in use‘.
There is no built in method to stop the device. Sorry.
