Ceph

Hi!
I'm trying to prepare an admin and server node with ceph-deploy.
I've configured SHH, hostnames and I've installed Ceph on my server node.
But when I create the monitor, the subdirectories bootstrap-mds and bootstrap-osd don't contain keyrings...

As consequence, when I execute ceph-deploy gatherkeys appear three warnings because don't find these keys.

I've tried to solve this error doing:

Disabling iptables and ufw.
Checking user's permissions
Checking hostnames

I've followed all the steps that says in this thread http://tracker.ceph.com/issues/4924, and I've cloned the branch which solved a similar problem, but it don't works...

Could you give me a solution?

Thanks!!
