#. Add the initial monitor(s) to your Ceph configuration file. ::
- mon initial members = {hostname}[,{hostname}]
+ mon_initial_members = {hostname}[,{hostname}]
For example::
- mon initial members = mon-node1

#. Add the IP address(es) of the initial monitor(s) to your Ceph configuration
file and save the file. ::
- mon host = {ip-address}[,{ip-address}]

For example::
- mon host = 192.168.0.1
+ mon_host = 192.168.0.1
**Note:** You may use IPv6 addresses instead of IPv4 addresses, but
- you must set ``ms bind ipv6`` to ``true``. See `Network Configuration
+ you must set ``ms_bind_ipv6`` to ``true``. See `Network Configuration
Reference`_ for details about network configuration.
#. Create a keyring for your cluster and generate a monitor secret key. ::

In the foregoing example, the ``[global]`` section of the configuration might
look like this::

- mon initial members = mon-node1
- mon host = 192.168.0.1

- osd journal size = 1024
- osd pool default size = 3
- osd pool default min size = 2
- osd pool default pg num = 333
- osd pool default pgp num = 333
- osd crush chooseleaf type = 1

#. Start the monitor(s).
Once you have your initial monitor(s) running, you should add OSDs. Your cluster
cannot reach an ``active + clean`` state until you have enough OSDs to handle the
-number of copies of an object (e.g., ``osd pool default size = 2`` requires at
+number of copies of an object (e.g., ``osd_pool_default_size = 2`` requires at
least two OSDs). After bootstrapping your monitor, your cluster has a default
CRUSH map; however, the CRUSH map doesn't have any Ceph OSD Daemons mapped to
a Ceph Node.
The ``ceph-volume`` utility automates the steps of the `Long Form`_ below. To
create the first two OSDs with the short form procedure, execute the following for each OSD:
-bluestore
-^^^^^^^^^
#. Create the OSD. ::
copy /var/lib/ceph/bootstrap-osd/ceph.keyring from monitor node (mon-node1) to /var/lib/ceph/bootstrap-osd/ceph.keyring on osd node (osd-node1)
sudo ceph-volume lvm activate 0 a7f64266-0894-4f1e-a635-d0aeaca0e993
-filestore
-^^^^^^^^^
-#. Create the OSD. ::
-
- ssh {osd node}
- sudo ceph-volume lvm create --filestore --data {data-path} --journal {journal-path}
-
- For example::
-
- ssh osd-node1
- sudo ceph-volume lvm create --filestore --data /dev/hdd1 --journal /dev/hdd2
-
-Alternatively, the creation process can be split in two phases (prepare, and
-activate):
-
-#. Prepare the OSD. ::
-
- ssh {node-name}
- sudo ceph-volume lvm prepare --filestore --data {data-path} --journal {journal-path}
-
- For example::
-
- ssh osd-node1
- sudo ceph-volume lvm prepare --filestore --data /dev/hdd1 --journal /dev/hdd2
-
- Once prepared, the ``ID`` and ``FSID`` of the prepared OSD are required for
- activation. These can be obtained by listing OSDs in the current server::
-
- sudo ceph-volume lvm list
-
-#. Activate the OSD::
-
- sudo ceph-volume lvm activate --filestore {ID} {FSID}
-
- For example::
-
- sudo ceph-volume lvm activate --filestore 0 a7f64266-0894-4f1e-a635-d0aeaca0e993
