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!
