Any other log messages from
tcmu-runner? Do you have a "/usr/lib64/tcmu-runner/handler_rbd.so" file?
Perhaps enable debug-level logging in "/etc/tcmu/tcmu.conf" and see if
that helps.

hm originally I took it from the gluster40 repository from the Centos
Storage SIG.

I tried the version:
https://1.chacra.ceph.com/r/tcmu-runner/master/7d0023e73855a42ac25038403387ab41ca10753a/centos/7/flavors/default/x86_64/tcmu-runner-1.3.0-89.g7d0023e.el7.x86_64.rpm
(because the version number from the storage SIG was a 1.3.0-rc4 which
seemed a bit low). That resulted also in the error above.
Now I tried the version from
https://1.chacra.ceph.com/r/tcmu-runner/master/b7498c0857a77f61616b8ad86c775ae39f9c119d/centos/7/flavors/default/x86_64/
but the error persists.
I am however able to map and unmap the image on the host using rbd map
and unmap commands.

Bernhard
