NAME
kpartx - Create device maps from partition tables.
SYNOPSIS
kpartx [-a|-d|-u|-l] [-r] [-p] [-f] [-g] [-s|-n] [-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. | ||
|
-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
