NAME
cryptsetup-erase, cryptsetup-luksErase - erase all keyslots
SYNOPSIS
cryptsetup erase [<options>] <device>
cryptsetup luksErase [<options>] <device>
DESCRIPTION
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].
OPTIONS
--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.
--header <device or file storing the LUKS header>
Use to specify detached LUKS2 header when erasing HW OPAL enabled
data device.
--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

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