| 124 | | Here is how the Ceph diagram works: |
| 125 | | 1. Data arrives to the file system/pool |
| 126 | | 2. Splits into chunks (pool groups) |
| 127 | | 3. Metadata and replicas are created and then stored into OSDs. |

| | 122 | This week, we spent most of our time focusing on the manual side installation of Ceph. In order for us to do it, we set up the manager as well as the monitor service setup. We also set up the dashboard, storage pool, file system, and also the CephFS setup. After that, we went over Ansible tasks and went. over how to work with Ansible tasks using yaml scripts which are also known as the Ansible playbooks. We then created playbooks in order for us to be able to fix hostname tasks. After that, the final thing that we did was to setup the LXC ansible container in order for us to test further configurations. We used passwordless sudo, deployed Ceph on one node, and created an Ansible playbook in order for us to mount the Ceph FS. |

| | 139 | **Summary** |
| | 140 | - Further Benchmarking |
| | 141 | - Created the poster |
| | 142 | - Worked on the final presentation for the program |
| | 143 | |
| | 144 | **Idea Of Our Progress This Week** |
| | 145 | We did not do very much this week except for finalizing the portfolio for the project and also doing some final run throughs and testing as well. The main work that we did do however was to work with a 3 node Ceph cluster. We ran benchmarks on 3 node Ceph clusters and ran fio as well on a mounted file system on node08. The final thing that we did was to model disaster recovery. |
