Once completed, we can run a file system called fsck on the image to make sure that it has been recovered correctly. In this case, the RBD was formatted with ext4, so we can use the e2fsck tool to check the image:
sudo e2fsck test.raw

Now we can finally mount the image as a loopback device to access our data. If the command returns no output, we have successfully mounted it:
sudo mount -o loop test.raw /mnt
You can see that the image is successfully mounted as a loop device:
