KPARTX(8) Linux Administrator's Manual KPARTX(8)
NAME
kpartx - Create device maps from partition tables
SYNOPSIS
kpartx [-a | -d | -l] [-v] wholedisk
DESCRIPTION
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
-r Read-only partition mappings
-d Delete partition mappings
-u Update partition mappings
-l List partition mappings that would be added -a
-p set device name-partition number delimiter
-f force creation of mappings; overrides 'no_partitions' feature
-g force GUID partition table (GPT)
-v Operate verbosely
-s Sync mode. Don't return until the partitions are created
EXAMPLE
To mount all the partitions in a raw disk image:
kpartx -av disk.img
This will output lines such as:
loop3p1 : 0 20964762 /dev/loop3 63
The loop3p1 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/loop3p1
When you're done, you need to remove the devices:
kpartx -d disk.img
