The above will produce three OSDs which run on `/dev/sdb`, `/dev/sdc`,
|
||||
and `/dev/sdd` which all journal to `/dev/sde`. This same setup will
|
||||
be duplicated per Ceph storage node and assumes uniform hardware.
|

If the journals will reside on the same disks as the OSDs then the
|

above should be changed to the following::

parameter_defaults:

CephAnsibleDisksConfig:

devices:

- /dev/sdb

- /dev/sdc

- /dev/sdd
|

osd_scenario: collocated

The `parameter_defaults` like the above may be saved in an environment
|

file "~/my-ceph-settings.yaml" and added to the deploy commandline::
