My first test setup

[dinkohrzica]

Hi all,

I have a question regarding setup. I wish to deploy two node HA i have 3 nodes with drac cards and each have 2 nic.
On first there will be clean install with 2x1tb disk, on 2nd I have solusvm and I would transfer my 3 vps's openvz - to proxmox and then Ill install proxmox on 2nd node.

My questions are:
1. any suggestion how to make this happen "the most painfull free way"
2. I have 3rd node too but I plan to leave solusvm there on xen but can I "plug" in 2 more disks and install proxmox as 3rd node there? Or just use it as quorum member? How?
I bought licence for 1st node 2 cpu, so I need 2 more with 2 cpu or how?

Later on I might use 3rd node fully for ceph...is it hard to turn it on or there is no way?
What about if I put 2x2 tb disks in each machine later on?...bit confused. Thanks

Thanks a lot for your suggestions.
Regards!

Hi,
1. depends on your Storage/network-config. If you plan to use ceph it's allways an good idea to use an own nic for the osd-traffic.

2.a Don't know solusvm but if your guests are CTs, the data are stored local (or on nfs). Ceph, DRBD and so on (which is usefull for HA) work's wit VMs (kvm) only.
For CT's (and HA) imho you need an redundant NFS-Server.

2.b for HA you should use three nodes (but I don't have real experiences with HA - I move and start the VMs manualy).

You need licenses for all sockets in the cluster, but you can mix of course servers like you want (like 2 hosts with 4 sockets an one with 1 socket).
You can ceph install later without problem - the live-migration for storage (kvm-only) is very nice for that.
