|
cryptsetup-resize - resize an active mapping
|
|
|
|
== SYNOPSIS
|
|
|
|
*cryptsetup _resize_ [<options>] <name>*
|
|
|
|
== DESCRIPTION
|
|
|
|
Resizes an active mapping <name>.
|
|
|
|
If --size (in 512-bytes sectors) or --device-size are not specified, the
|
|
size is computed from the underlying device. For LUKS it is the size of
|
|
the underlying device without the area reserved for LUKS header (see
|
|
data payload offset in *luksDump* command). For plain crypt device, the
|
|
whole device size is used.
|
|
|
|
Note that this does not change the raw device geometry, it just changes
|
|
how many sectors of the raw device are represented in the mapped device.
|
|
|
|
If cryptsetup detected volume key for active device loaded in kernel
|
|
keyring service, resize action would first try to retrieve the key using
|
|
a token. Only if it failed, it'd ask for a passphrase to unlock a
|
|
keyslot (LUKS) or to derive a volume key again (plain mode). The kernel
|
|
keyring is used by default for LUKS2 devices.
|
|
|
|
With LUKS2 device additional *<options>* can be [--token-id,
|
|
--token-only, --token-type, --key-slot, --key-file, --keyfile-size,
|
|
--keyfile-offset, --timeout, --disable-external-tokens, --disable-locks,
|
|
--disable-keyring].
