CRYPTSETUP-ERASE(8) Maintenance Commands CRYPTSETUP-ERASE(8)
cryptsetup-erase, cryptsetup-luksErase - erase all keyslots
cryptsetup erase [<options>] <device>
cryptsetup luksErase [<options>] <device>
Erase all keyslots and make the LUKS container permanently
inaccessible. Unless the device is configured with HW OPAL
support you do not need to provide any password for this
operation.
WARNING: This operation is irreversible.
WARNING: with --hw-opal-factory-reset ALL data is lost on the
device, regardless of the partition it is ran on, if any, and
regardless of any LUKS2 header backup, and does not require a
valid LUKS2 header to be present on the device to run.
<options> can be [--header, --disable-locks,
--hw-opal-factory-reset, --key-file].
--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 to specify detached LUKS2 header when erasing HW OPAL
enabled data device.
--help, -?
Show help text and default parameters.
--hw-opal-factory-reset
Erase ALL data on the OPAL self-encrypted device, regardless
of the partition it is ran on, if any, and does not require a
valid LUKS2 header to be present on the device to run. After
providing correct PSID via interactive prompt or via
--key-file parameter the device is erased. PSID is usually
printed on the OPAL device label (either directly or as a QR
code).
--key-file, -d name (LUKS2 with HW OPAL only)
Read the Admin PIN or PSID (with --hw-opal-factory-reset)
from file depending on options used.
If the name given is "-", then the secret will be read from
stdin. In this case, reading will not stop at newline
characters.
--usage
Show short option help.
--version, -V
Show the program version.
Report bugs at cryptsetup mailing list
<[email protected]> or in Issues project section
<https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
Please attach output of the failed command with --debug option
added.
