I failed to use it on lab, but it seems more recommended. Where did you get it from that ansible is recommended? Ansible is a tool to help you automate deployments, but I have the impression it is mostly used as a 'I do not know how to install something' so lets use ansible tool. >- Install Ceph Nautilus > >- Each server will host OSD, MON, MGR and MDS. >- One VM for ceph-admin: This wil be used to run ceph-ansible and maybe to host some ceph services later Don't waste a vm on this? >- I'll have to serve samba, iscsi and probably NFS too.

Now I've been asked to do a production setup using 3 servers (Dell R740) with 12 4TB each. My plan is this: - Use 2 HDDs for SO using RAID 1 (I've left 3.5TB unallocated in case I can use it later for storage) - Install CentOS 7.7 - Use 2 vLANs, one for ceph internal usage and another for external access. Since they've 4 network adapters, I'll try to bond them in pairs to speed up network (1Gb). - I'll try to use ceph-ansible for installation. I failed to use it on lab, but it seems more recommended. - Install Ceph Nautilus - Each server will host OSD, MON, MGR and MDS. - One VM for ceph-admin: This wil be used to run ceph-ansible and maybe to host some ceph services later - I'll have to serve samba, iscsi and probably NFS too. Not sure how or on which servers. Am I missing anything? Am I doing anything "wrong"? I searched for some actual guidance on setup but I couldn't find anything complete, like a good tutorial or reference based on possible use-cases. So, is there any suggestions you could share or links and references I should take a look?
