6 cryptsetup-luksUUID - print or set the UUID of a LUKS device
7
9 cryptsetup luksUUID [<options>] <device>
10
12 Print the UUID of a LUKS device.
13 Set new UUID if --uuid option is specified.
14
15 <options> can be [--header, --uuid, --type, --disable-locks].
16
18 --type <device-type>
19 Specifies required device type, for more info read BASIC ACTIONS
20 section in cryptsetup(8).
21
22 --uuid <UUID>
23 Use the provided UUID for the luksFormat command instead of
24 generating a new one. Changes the existing UUID when used with the
25 luksUUID command.
26
27 The UUID must be provided in the standard UUID format, e.g.
28 12345678-1234-1234-1234-123456789abc.
29
30 --header <device or file storing the LUKS header>
31 Use a detached (separated) metadata device or file where the LUKS
32 header is stored. This option allows one to store ciphertext and
33 LUKS header on different devices.
34
35 For commands that change the LUKS header (e.g. luksAddKey), specify
36 the device or file with the LUKS header directly as the LUKS
37 device.
38
39 --disable-locks
40 Disable lock protection for metadata on disk. This option is valid
41 only for LUKS2 and ignored for other formats.
42
43 WARNING: Do not use this option unless you run cryptsetup in a
44 restricted environment where locking is impossible to perform
45 (where /run directory cannot be used).
46
47 --batch-mode, -q
48 Suppresses all confirmation questions. Use with care!
49
50 If the --verify-passphrase option is not specified, this option
51 also switches off the passphrase verification.
52
53 --debug or --debug-json
54 Run in debug mode with full diagnostic logs. Debug output lines are
55 always prefixed by #.
56
57 If --debug-json is used, additional LUKS2 JSON data structures are
58 printed.
59
60 --version, -V
61 Show the program version.
62
63 --usage
64 Show short option help.
65
66 --help, -?
67 Show help text and default parameters.
68
70 Report bugs at cryptsetup mailing list <cryptsetup@lists.linux.dev> or
71 in Issues project section
72 <https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
73
74 Please attach output of the failed command with --debug option added.
