Re: Documentation Error - Manual Deployment - Monitor Bootstrapping

[Dyweni - Ceph-Devel <YS3fpFE2ykfB@dyweni.com>]

So after reading other documentation areas:

   http://ceph.com/docs/master/rados/configuration/mon-config-ref/
   http://ceph.com/docs/master/rados/configuration/ceph-conf/#monitors

I arrive at the following (working) config file:
-------
[global]
fsid = e3e1a87b-d282-41b5-b4ad-fb3f969e164f

[mon]
mon initial members = a

[mon.a]
host = cephmon
mon addr = 1.2.3.4:6789
-------



I also discovered that steps # 12 and # 13 are faulty.
  - In both steps, the {hostname} should actually be the monitors ID, not 
hostname.
  - So the correct commands are:
      sudo mkdir /var/lib/ceph/mon/{cluster-name}-{id}
      ceph-mon --mkfs -i {id} --monmap /tmp/monmap --keyring 
/tmp/ceph.mon.keyring

Thanks,
Dyweni
