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
