CRYPTSETUP-LUKSUUID(8) Maintenance Commands CRYPTSETUP-LUKSUUID(8)
cryptsetup-luksUUID - print or set the UUID of a LUKS device
cryptsetup luksUUID [<options>] <device>
Print the UUID of a LUKS device. Set new UUID if --uuid option is specified. <options> can be [--header, --uuid, --type, --disable-locks].
--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. --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). --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. --help, -? Show help text and default parameters. --type <device-type> Specifies required device type, for more info read BASIC ACTIONS section in cryptsetup(8). --usage Show short option help. --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. --version, -V Show the program version.
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.
