I have tested Ceph using VMs but never got to put it to use and had a lot of trouble to get it to install.
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
- 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?
Thanks;
