KPARTX(8)                              System Manager's Manual                             KPARTX(8)



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
