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

-l

List partition mappings that would be added -a

-p

set device name-partition number delimiter

-g

force GUID partition table (GPT)

-v

Operate verbosely

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
