Cryptsetup compains not a valid device

Hi,

We have a disk say /dev/sdx which is encrypted as whole disk (no partition)

Now after extending the disk and resizing the file system the cryptsetup comamnd compains that /dev/sdx is not a vaild LUKS device.

[xxxxxxxxxxxxxx]# cryptsetup luksOpen /dev/sdx sdxEncrypted
Device /dev/sdx is not a valid LUKS device.

Do I need to change anything with fdisk?

Quick Help is much appreciated.

SYSTEMD-CRYPTSETUP@.SERVICE(8)				    systemd-cryptsetup@.service 			    SYSTEMD-CRYPTSETUP@.SERVICE(8)

NAME

       systemd-cryptsetup@.service, systemd-cryptsetup - Full disk decryption logic

SYNOPSIS

       systemd-cryptsetup@.service

       /usr/lib/systemd/systemd-cryptsetup

DESCRIPTION

       systemd-cryptsetup@.service is a service responsible for setting up encrypted block devices. It is instantiated for each device that
       requires decryption for access.

       systemd-cryptsetup@.service will ask for hard disk passwords via the password agent logic[1], in order to query the user for the password
       using the right mechanism at boot and during runtime.

       At early boot and when the system manager configuration is reloaded this /etc/crypttab is translated into systemd-cryptsetup@.service units
       by systemd-cryptsetup-generator(8).

       systemd(1), systemd-cryptsetup-generator(8), crypttab(5), cryptsetup(8)
