I am trying to deploy a cluster with ceph-deploy. I installed ceph
0.72.2 from the rpm repositories. Running "ceph-deploy mon
create-initial" creates /var/lib/ceph etc. on all the nodes, but on
all nodes I get a warning:
[hvrrzceph2][DEBUG ] Starting Ceph mon.hvrrzceph2 on hvrrzceph2...
[hvrrzceph2][DEBUG ] Starting ceph-create-keys on hvrrzceph2...
[hvrrzceph2][WARNING] No data was received after 7 seconds,
disconnecting...
and afterwards, ceph -s cannot connect to the cluster. No
client.admin keyring is created in ceph.conf.
Then I attempted to create one monitor only on one node. Again, no
keys for client.admin, bootstrap-mds and bootstrap-osd were created.
Here is the complete log of this attempt:

I had already a running cluster, and ceph-deploy had worked ... :-(
Any hints where I can find what is missing?
TIA.
