Good evening, I'm new to the forum, I wanted to ask you for advice, I have to build a system of two server clusters, I had thought of using PROXMOX since I used it in the office since January 2019. The system must allow me to have two servers with its virtual machines CENTOS 7 , if one of the two serer fails for some reason the second server must take over. The two CENTOS virtual machines will work by putting data on an external NFS (network NAS).
From vs. experience can I deal with the problem with PROXMOX?

No, you cannot with only two servers. You need at least a third quorum node.

Why don't you just install CentOS on the two servers and build your HA service with corosync or some other HA software?

Hi,

Yes you can do it. I use this setup(2 nodes only) starting from 2018(using reliable network devices). But why you want to use fail-over ? Load balancing is better. Do you want one node to do nothing most of the time?

Good luck / bafta.

Buongiorno,
Vorrei farlo con proxmox per sfruttare la possibilità di fare anche il backup dell'intera macchina virtuale all'interno del nodo, in modo da poter ripristinare i miei server in qualsiasi momento anche su un nodo proxmox dotato di fortuna in caso di bloccarsi.
Su proxmox devo mettere 3 macchine Linux CENTOS (cluster con secondo nodo) che dovranno essere accessibili da circa 20/25 lavori sulla LAN. Potrei avere un calo delle prestazioni configurando anche il cluster?
