CRYPTSETUP-CLOSE(8) Maintenance Commands CRYPTSETUP-CLOSE(8)
NAME
cryptsetup-close - removes the existing mapping <name> (and the
associated key)
SYNOPSIS
cryptsetup close [<options>] <name>
DESCRIPTION
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].
OPTIONS
--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.
--deferred
Defers device removal in close command until the last user closes
it.
--cancel-deferred
Removes a previously configured deferred device removal in close
command.
--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.
