9 kpartx [-a|-d|-u|-l] [-r] [-p] [-f] [-g] [-s] [-v] wholedisk
10
12 This tool, derived from util-linux' partx, reads partition tables on
13 specified device and create device maps over partitions segments
14 detected. It is called from hotplug upon device maps creation and dele‐
15 tion.
16
18 -a Add partition mappings.
19
20 -d Delete partition mappings.
21
22 -u Update partition mappings.
23
24 -l List partition mappings that would be added -a.
25
26 -r Read-only partition mappings.
27
28 -p Set device name-partition number delimiter.
29
30 -f Force creation of mappings; overrides 'no_partitions' feature.
31
32 -g Force GUID partition table (GPT).
33
34 -s Sync mode. Don't return until the partitions are created.
35
36 -v Operate verbosely.
37
39 To mount all the partitions in a raw disk image:
40
41 kpartx -av disk.img
42
43 This will output lines such as:
44
45 add map loop1p1 (254:4): 0 409597 linear 7:1 3
46
47 The loop1p1 is the name of a device file under /dev/mapper which you
48 can use to access the partition, for example to fsck it:
49
50 fsck /dev/mapper/loop1p1
51
52 When you're done, you need to remove the devices:
53
54 kpartx -d disk.img
