Hi!
I am a beginner with no prior knowledge to all of this so please bear with me!

I have a Proxmox cluster with a Ceph pool and all nodes in a HA group. One of these nodes died out and doesn't start up. I'd like to properly delete and remove this node, its Ceph OSDs and monitors, and downsize my cluster size by further removing another node.
So, for the dead node, I deleted the node using pvecm delnode <.> and restarted the cluster. I also deleted its Ceph osd using ceph osd purge <.> and deleted the monitor using ceph mon remove <.>. How do I go about deleting the monitor and any other remnant ceph or related config?

I'd also like to remove another node that still starts up. Please help me out with a proper guide to delete nodes, any Ceph related stuff and reduce my cluster size!!!

I'd like any help possible...
Thank you!
