kpartx - Create device maps from partition tables.
kpartx [-a|-d|-u|-l] [-r] [-p] [-f] [-g] [-s|-n] [-v] wholedisk
This tool, derived from util-linux' partx, reads partition tables on specified device and create device maps over partitions segments detected. It is called from hotplug upon device maps creation and deletion.
- Add partition mappings.
- Delete partition mappings.
- Update partition mappings.
- List partition mappings that would be added -a.
- Read-only partition mappings.
- Set device name-partition number delimiter.
- Force creation of mappings; overrides 'no_partitions' feature.
- Force GUID partition table (GPT).
- Sync mode (Default). Don't return until the partitions are created.
- Nosync mode. Return before the partitions are created.
- Operate verbosely.
To mount all the partitions in a raw disk image:
- kpartx -av disk.img
This will output lines such as:
- add map loop1p1 (254:4): 0 409597 linear 7:1 3
The loop1p1 is the name of a device file under /dev/mapper which you can use to access the partition, for example to fsck it:
- fsck /dev/mapper/loop1p1
When you're done, you need to remove the devices:
- kpartx -d disk.img
