cryptsetup-close - removes the existing mapping <name> (and the associated key)


cryptsetup close [<options>] <name>


Removes the existing mapping <name> and wipes the key from kernel memory.

For backward compatibility, there are close command aliases: remove, plainClose, luksClose, loopaesClose, tcryptClose, bitlkClose (all behave exactly the same, device type is determined automatically from the active device).

<options> can be [--deferred, --cancel-deferred, --header, --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.


Removes a previously configured deferred device removal in close command.

--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.


Defers device removal in close command until the last user closes it.


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.


Show short option help.

--version, -V

Show the program version.


Report bugs at cryptsetup mailing list <cryptsetup [AT]> or in Issues project section <>;.

Please attach output of the failed command with --debug option added.
