run "dmsetup info -c" and check UUID for all devices which have CRYPT- prefix.

run "cryptsetup luksDump /dev/mapper/vg0-services_var services_var", see UUID field

and check that there is no active device from dmsetup above with that UUID (ignore CRYPT- prefix).

If so, it is why it fails - --non-exclusive as side effect create device without UUID set,
so for kernel it is new device and allows its creation.

If there is no device with the same UUID, it is probably different problem.
