CRYPTSETUP-LUKSUUID(8) Maintenance Commands CRYPTSETUP-LUKSUUID(8)
NAME
cryptsetup-luksUUID - print or set the UUID of a LUKS device
SYNOPSIS
cryptsetup luksUUID [<options>] <device>
DESCRIPTION
Print the UUID of a LUKS device.
Set new UUID if --uuid option is specified.
<options> can be [--header, --uuid, --type, --disable-locks].
OPTIONS
--type <device-type>
Specifies required device type, for more info read BASIC ACTIONS
section in cryptsetup(8).
--uuid <UUID>
Use the provided UUID for the luksFormat command instead of
generating a new one. Changes the existing UUID when used with the
luksUUID command.
The UUID must be provided in the standard UUID format, e.g.
12345678-1234-1234-1234-123456789abc.
--header <device or file storing the LUKS header>
Use a detached (separated) metadata device or file where the LUKS
header is stored. This option allows one to store ciphertext and
LUKS header on different devices.
For commands that change the LUKS header (e.g. luksAddKey), specify
the device or file with the LUKS header directly as the LUKS
device.
--disable-locks
Disable lock protection for metadata on disk. This option is valid
only for LUKS2 and ignored for other formats.
WARNING: Do not use this option unless you run cryptsetup in a
restricted environment where locking is impossible to perform
(where /run directory cannot be used).
--batch-mode, -q
Suppresses all confirmation questions. Use with care!
If the --verify-passphrase option is not specified, this option
also switches off the passphrase verification.
--debug or --debug-json
Run in debug mode with full diagnostic logs. Debug output lines are
always prefixed by #.
If --debug-json is used, additional LUKS2 JSON data structures are
printed.
--version, -V
Show the program version.
--usage
Show short option help.
--help, -?
Show help text and default parameters.
REPORTING BUGS
Report bugs at cryptsetup mailing list <cryptsetup@lists.linux.dev> or
in Issues project section
<https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
Please attach output of the failed command with --debug option added.
