Mount Partitions in Disk Image

If you have a recent kernel, and pass loop.max_part=63 on boot (if loop is built-in) or to modprobe (if loop is a module).

1. Mount image as loop device

   # losetup /dev/loop0 rpool.img

2. Run partprobe

   # partprobe /dev/loop0

3. Finish

   # ls /dev/loop0* -l
   brw-rw---- 1 root disk   7, 0 Mar 26 13:23 /dev/loop0
   brw-rw---- 1 root disk 259, 0 Mar 26 13:23 /dev/loop0p1
   brw-rw---- 1 root disk 259, 1 Mar 26 13:23 /dev/loop0p9

1. Unload loop device

   # losetup -d /dev/loop0

1. Mount image as loop device

   # losetup /dev/loop0 rpool.img

2. List partitions in loop

   # kpartx -l /dev/loop0
   loop0p1 : 0 44019712 /dev/loop0 2048
   loop0p9 : 0 16384 /dev/loop0 44021760

3. Create device mappings of partitions

   # kpartx -av /dev/loop0
   add map loop0p1 (252:0): 0 44019712 linear 7:0 2048
   add map loop0p9 (252:1): 0 16384 linear 7:0 44021760

4. Finish

   # ls /dev/mapper/loop0* -l
   lrwxrwxrwx 1 root root       7 Mar 26 13:16 loop0p1 -> ../dm-0
   lrwxrwxrwx 1 root root       7 Mar 26 13:16 loop0p9 -> ../dm-1

1. Disconnect the device map files using kpartx

   # kpartx -dv /dev/loop0
   del devmap : loop0p9
   del devmap : loop0p1

2. Unload loop device

   # losetup -d /dev/loop0
