1CRYPTSETUP-CLOSE(8) Maintenance Commands CRYPTSETUP-CLOSE(8)
2
3
4
6 cryptsetup-close - removes the existing mapping <name> (and the
7 associated key)
8
10 cryptsetup close [<options>] <name>
11
13 Removes the existing mapping <name> and wipes the key from kernel
14 memory.
15
16 For backward compatibility, there are close command aliases: remove,
17 plainClose, luksClose, loopaesClose, tcryptClose, bitlkClose (all
18 behave exactly the same, device type is determined automatically from
19 the active device).
20
21 <options> can be [--deferred, --cancel-deferred, --header,
22 --disable-locks].
23
25 --header <device or file storing the LUKS header>
26 Use a detached (separated) metadata device or file where the LUKS
27 header is stored. This option allows one to store ciphertext and
28 LUKS header on different devices.
29
30 For commands that change the LUKS header (e.g. luksAddKey), specify
31 the device or file with the LUKS header directly as the LUKS
32 device.
33
34 --deferred
35 Defers device removal in close command until the last user closes
36 it.
37
38 --cancel-deferred
39 Removes a previously configured deferred device removal in close
40 command.
41
42 --disable-locks
43 Disable lock protection for metadata on disk. This option is valid
44 only for LUKS2 and ignored for other formats.
45
46 WARNING: Do not use this option unless you run cryptsetup in a
47 restricted environment where locking is impossible to perform
48 (where /run directory cannot be used).
49
50 --batch-mode, -q
51 Suppresses all confirmation questions. Use with care!
52
53 If the --verify-passphrase option is not specified, this option
54 also switches off the passphrase verification.
55
56 --debug or --debug-json
57 Run in debug mode with full diagnostic logs. Debug output lines are
58 always prefixed by #.
59
60 If --debug-json is used, additional LUKS2 JSON data structures are
61 printed.
62
63 --version, -V
64 Show the program version.
65
66 --usage
67 Show short option help.
68
69 --help, -?
70 Show help text and default parameters.

74 in Issues project section
75 <https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
76
77 Please attach output of the failed command with --debug option added.
