Getting Started?

[VC-Mike]

Hello,

I'm a little confused with getting started on Proxmox, I've set it up on a VM for testing purposes until our main CP server becomes available and found the installation instructions in the wiki with ease, the installation was a breeze! But what next? I can't seem to find any instructions on where to go or where to start next, it just goes straight into creating VM's and containers.

I'm looking to setup a KVM HA cluster.

Sorry if I sound stupid

Thanks in advance!

the wiki is your friend, start from here:
http://pve.proxmox.com/wiki/High_Availability_Cluster
or here if you have just two nodes
http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster

but read all wiki also keeping in mind that pve is changing faster than wiki, so check if everything applies to your version/setup... there are so many things that could be done differently, so after reading, search forum with put smart keywords, or put specific and detailed questions on forums

I'm a little confused to how Proxmox works with a central control panel as I only see 1 set of installation instructions. I'm guessing all the servers in the cluster share the same installation procedure? When purchasing a subscription it mentions sockets but we wouldn't want to be paying for the sockets on our control panel server. Our direction at this time is as follows;

1x Control Panel Server & Backup Storage (2x SSD for OS - 8x 2TB RAID10 Backup/ISO/Template etc Storage).
4x Hypervisors (2x SSD for OS - 32GB RAM each).
1x FreeNAS/OmniOS_Napp-it SAN (2x SSD for OS - 10/14x 2TB ZFS RAIDz2 for VM Storage).

Could anyone provide some insight on best practices for configuring this correctly? We're looking to hire a freelancer as well to help through the process, however, if I was able to be directed toward the correct wiki articles in order to do all of this myself, I'd be quite able to.

Thanks,

Mike

As I read it then you will have 5 (1 + 4) servers running Proxmox?

If the 5 servers have 1 CPU each then you will need 5 licenses given that you want a license.

The procedure will then be:
1) Install the default proxmox from iso on all 5 servers
2) Then follow this howto to create the cluster: https://pve.proxmox.com/wiki/High_Availability_Cluster_:_Simple_version

...remember that pve works as a multi master cluster (cman), so any node can have full control of all nodes and all operations between them (backup, migrations, storages, etc).

That is why there's only 1 procedure set.

I've never used them, but from what I've read, an exception could be that you can have also pve nodes hosting "ceph" storage (also managed by pve), so in your cluster you could have (3+) nodes "dedicated" to ceph storage (since you probably don't wish to mix virt and ceph storage on a single node), but even ceph nodes are "cluster masters", and you can log into their interface and fully manage also all other nodes: you just "select" the node you need from the web gui, and you're "there"...
It's a wonderful advantage...
