Hi all,
approaching ceph today for the first time, so apologize for the basic
questions I promise I will do all my homework :-)
Following the documentation "storage cluster quick start" I am soon
stuck with the issue below while creating a first mon:
ceph-admin # ceph-deploy mon create ceph-node1
[ceph_deploy.cli][INFO ] Invoked (1.3.3): /usr/bin/ceph-deploy mon

It seems ceph-mon does not exit with success, in fact:
