How to mount sd-card image created with dd?

rated 0 times [ 27] [ 0] / answers: 1 / hits: 65401 / 3 Years ago, sun, may 23, 2021, 1:46:11

I have created an image of my Raspberry Pi SD-card using dd:

sudo dd if=/dev/sdf of=/home/myusername/raspberry-backup-2014-04-10.img

The SD-card includes two partitions (one vfat, one ext4) which are automatically mounted when I plug the card in.

My question: How can I mount these partitions from the .img file?

More details:

$ fdisk -l raspberry-backup-2014-04-10.img

After some additonal testing I found the solution myself: kpartx

sudo kpartx -a raspberry-backup-2014-04-10.img

This command created /dev/mapper/loop0p1 and /dev/mapper/loop0p2. Afterwards these partitions can be mounted straight forward:

sudo mount -o rw -t ext4 /dev/mapper/loop0p2 mount_target/
