ceph.conf Configuration
-----------------------
The supported method for defining your ceph.conf is to use the ``ceph_conf_overrides`` variable. This allows you to specify configuration options using
an INI format. This variable can be used to override sections already defined in ceph.conf (see: ``roles/ceph-common/templates/ceph.conf.j2``) or to provide
new configuration options. The following sections in ceph.conf are supported: [global], [mon], [osd], [mds] and [rgw].
An example::
ceph_conf_overrides:
global:
foo: 1234
bar: 5678
osd:
osd_mkfs_type: ext4
.. note::
We will no longer accept pull requests that modify the ceph.conf template unless it helps the deployment. For simple configuration tweaks
please use the `ceph_conf_overrides` variable.
Full documentation for configuring each of the ceph daemon types are in the following sections.
