**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.

## Special notes

If you are looking at deploying a Ceph version older than Jewel.
It is highly recommended that you apply the following settings to your `group_vars/all` file on the `ceph_conf_overrides` variable:

```
ceph_conf_overrides:
osd:
osd recovery max active: 5
osd max backfills: 2
osd recovery op priority: 2
osd recovery threads: 1
```
