Hallo,
thank you very much for anyone taking the time to read this.
I am using a Thinkpad Edge E145 with Ubuntu 14.04 installed.
I have recently reinstalled Ubuntu to a new HD. This installation is
LUKS encrypted LVM and works without problems.
My old installation on a LVM Luks encrypted drive would no longer start up.
I had deleted old kernels. Maybe the problems are related to that.
Now I can no longer mount the old LVM Luks encrypted drive when I plug
it in to the notebook through a USB port.
Here is the present situation in nautilus:

Here I have the additional cog wheel options to:
Edit partition
Change pass phrase
Edit Encryption options
This is the situation in the terminal:
