Hi Manuel
I am Goncalo Borges (Portuguese) and I work at the university of Sydney. We have been using ceph and cephfs since almost two years. If you think worthwhile, we can just talk and discuss our experiences. There is good ceph community in Melbourne but you are actually the first one in Sydney that I am aware off.
Cheers
Goncalo

Subject: installation docs
Hi,
I just would like to point a couple of issues I have following the INSTALLATION (QUICK) document.
1. The order to clean ceph deployment is:
a. Ceph-deploy purge {ceph-node} [{ceph-node}]
b. Ceph-deploy purgedata {ceph-node} [{ceph-node}]
2. I run ceph jewel 10.2.5 and “eph-deploy preapre” also activates the OSD, this is something that confused me because I could not understand why there was 3 commands (prepare_activate or create) to do this when only 1 is needed (right now I don’t know the difference between prepare and create as for me both do the same)
3. Right after the installation the status of the ceph cluster is “HEALTH_WARN too few PGs per OSD (10 < min 30)” and not “active + clean” as the documentation says.
4. It would be good to add a small guide for troubleshooting like check if the monitors are working, how to restart the monitor processes, check communication between the OSDs processes and the monitors, run commands on the local nodes to see in more details what is failing, etc.
5. Also I spent a lot of time from the IRC channel trying to understand why ceph-deploy and the problem was the disks were already mounted. I could not see in running df –h but lsblk, this is also something that in my opinion would be good to have. Special thanks to Ivve and badone who helped me to find out what the issue was.
6. Last thing, would be good to mention that installing ceph through Ansible is also an option
Other than that congratulation to the community for your effort and keep it going!
