Fail to attach volume: `iscsiadm set authmethod: exit status 21`

[kumy]

I'm trying to attach some volume from the OVH cloudstack but it fails with error below:

# docker volume create -d cinder --name test3 -o size=1 -o type=classic test3
# docker run -it --rm -v test3:/data ubuntu bash
docker: Error response from daemon: error while mounting volume '': VolumeDriver.Mount: exit status 21.

Here are the log output of cdd.
