| - `ceph-volume` was enhanced to better handle unexpected disk formats like Atari partitions and GPT based devices | ||
| - `cephadm` uses ssh as the control path to each cluster host. During our negative testing, we found that when ssh issues were encountered (bad/missing keys), the resulting information returned to the user was overly verbose. This was fixed in [PR 43880](https://github.com/ceph/ceph/pull/43880). | ||
| - Cephadm’s experimental 'agent' feature was used to provide the orchestrator with host, device and daemon state metadata. Testing showed that deployment and data quality were as expected, but the agent generated too much log traffic, making potential troubleshooting problematic. The intent is for the Agent to become a supported feature in the Ceph Reef release. |

| Getting a deeper understanding of the effects of scale on the metrics 'path' was a key finding, and formed the basis for further analysis work that will be covered in a subsequent blog. | ||

We could use a "quincy@scale" tag to bind all of these blog posts together. Otherwise, looks great to me!
@anthonyeleven do you think these can be addressed in a later PR? This PR was intended to be merged yesterday https://github.com/ceph/ceph.io/pull/408/files#diff-04d54a1f366be0c6924c573a3aa35605b0ebe2ac9ed1764ed0f6d1b27b8b6e5eR3 |
