Mount a partition from within a complete disk dump

lomount -diskimage /path/to/your/backup.img -partition 1 /mnt/foo
Instead of calculating the offset and providing an offset option to mount, let lomount do the job for you by just providing the partition number you would like to loop mount.

  • Suppose you made a backup of your hard disk with dd: dd if=/dev/sda of=/mnt/disk/backup.img This command enables you to mount a partition from inside this image, so you can access your files directly. Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img). Show Sample Output


    6
    INFILE=/path/to/your/backup.img; MOUNTPT=/mnt/foo; PARTITION=1; mount "$INFILE" "$MOUNTPT" -o loop,offset=$[ `/sbin/sfdisk -d "$INFILE" | grep "start=" | head -n $PARTITION | tail -n1 | sed 's/.*start=[ ]*//' | sed 's/,.*//'` * 512 ]

What Others Think

Just noticed that lomount seems not to be part of the standard distribution, but is integrated in the XEN add ons (xen-tools package here on SLES). But nevertheless there seem to be some other sources for this command ;-)
