:ACTION_LUKSSUSPEND:
== Name
cryptsetup-luksSuspend - suspends an active device and wipes the key
== SYNOPSIS
*cryptsetup _luksSuspend_ [<options>] <name>*
== DESCRIPTION
Suspends an active device (all IO operations will block and accesses to
the device will wait indefinitely) and wipes the encryption key from
kernel memory. Needs kernel 2.6.19 or later.
After this operation, you have to use _luksResume_ to reinstate the
encryption key and unblock the device or _close_ to remove the mapped
device.
*<options>* can be [--header, --disable-locks].
*WARNING:* Never suspend the device on which the cryptsetup binary
resides.
