+== Name
+
+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.
+
+*<options>* can be [--size, --device-size, --token-id, --token-only,
+--token-type, --key-slot, --key-file, --keyfile-size, --keyfile-offset,
+--timeout, --disable-external-tokens, --disable-locks, --disable-keyring,
+--verify-passphrase, --timeout].
