Hi all
I have a question regarding ceph storage for our kubernetes cluster.
We have 2 supermicros, Server 1 has a bunch of 120GB SSDs in RAID, while Server 2 has 4 1.8TB HDDs and a 120GB SSD for the OS. Both Running Proxmox v6.1-3
Currently we use ceph via rook to manage our storage but felt it'd be better if we decoupled storage from kubernetes to increase stability and make recovery easier in the event of kubernetes cluster failure.
My question is, can we use Server 2 for ceph storage while our VMs running kubernetes run on Server 1.
From my initial investigation it sounds like it's possible but not recommended to run ceph on less than 3 nodes? I assume that if we ever get more hardware I can add more storage to the ceph cluster (increasing it from one to two and maybe 3 nodes down the line). I also assume mixing VMs and ceph on a node is not recommended?
