kpartx [\| -a | -d | -u | -l \|] [\| -r \|] [\| -p \|] [\| -f \|] [\| -g \|] [\| -s | -n \|] [\| -v \|] wholediskDescription
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.Options
-a Add partition mappings.
-d Delete partition mappings.
-u Update partition mappings.
-l List partition mappings that would be added -a.
-r Read-only partition mappings.
-p Set device name-partition number delimiter.
-f Force creation of mappings; overrides 'no_partitions' feature.
-g Force GUID partition table (GPT).
-s Sync mode (Default). Don't return until the partitions are created.
-n Nosync mode. Return before the partitions are created.
-v Operate verbosely.
Example
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
