Is my understanding correct ? and would it be better if I swapped my 3TB with 1TB drives making it 2...

    [SOLVED] Optimal number of Ceph monitor/manager/MDS

    Hi all, I'm currently running a cluster with 15 nodes and I plan to add more in the near future. As for Ceph I have 5 monitors, 5 managers and 5 metadata servers which currently manage 60+ OSDs. Do you advice to add more monitors/mangers/mds? Should I stick with odd numbers because of quorum...

    Proxmox cluster scaling best practices

    Hello, I have a 5 node PVE cluster with Ceph (2 OSD every node on Intel DC SSD on dedicated 10G network). I am actually using it for LXC containers and my idea is to always keep one node empty to move containers in case of node failure. I will need to scale up in the near future probably to a...
