I want to learn ceph, and i am really having no knowledge on ceph.
I decided to follow the official doc on ceph.com site.
It is said to use ceph-deploy which is not working.
You could do like I did;
start gathering some Ceph know-how by targeting 3 x86_64 VMs running Fedora29, CentOS7 or RHEL7.
Once you are comfortable using ceph-ansible against these, try again with your raspberry3B+ machines.
Ok I finally was able to run ceph-ansible, ansible and all dependencies.
Here are my findings :
- regarding the ceph release from fedora29 repos (12.*)
ceph-ansible release should be 'stable-3.2' ('master' has a bug for this
ceph release)
- ansible should be installed using pip3
I am now able to run the ansible-playbook with the following result,
after 1h and 7min :)
