Removing a node from a cluster (rebuilding it with full-disk encryption)

Group,

I have a two-node Proxmox cluster. I want to remove a node from the cluster, and then rebuild it. The goal is to build a completely encrypted server physical volume so the physical drive is encrypted if it gets in the wrong hands. My understanding is the right way to do this is do a Debian base-build with LUKS encryption on the drive, then do a manual install of Proxmox.

So my plan is:
1. Pull the second server from the Proxmox cluster, since it's only a two-node cluster does this mean turning the cluster function off (how would I do this).

2. Install Debian base with LUKS, I imagine a good best practice is separate boot and data partitions. I'm working with a meaty server with 1 terabyte of storage. I'm thinking 100 gig boot, 90 gig data partitions.

3. Manually install Proxmox. I need instructions for this.

4. Rejoin (or I guess re-create the cluster.

Many thanks to all!

You can use pvecm
