There are certain storage sharing features of Proxmox that make it desirable (to me) to use a Proxmox host as a dedicated location to hold VM archives. This server would spend most of its time turned off. Are there any negatives to making it a member of a Proxmox cluster? This is assuming there are enough cluster members to not break quorum when my archive server is turned off. Can a Proxmox cluster member be offline for (going to extremes) a year, then get powered on and accepted back into the cluster without issue?

For example, if you have three Microsoft Active Directory Domain Controllers all serving the same domain, and you turn one of them off for a year, when you next start up that DC, that DC will have issues resuming its role of domain controller. You will probably have to demote/remove and add/promote that server so it can function as a DC again.
 
Hi,

You lose the vote of this member and so the capability of one failing node.
In a 3/4 node setup, if one node fail you loos the capability to manage the rest node/s.

Can a Proxmox cluster member be offline for (going to extremes) a year, then get powered on and accepted back into the cluster without issue?
Never test this, but theoretically yes because there is a config version number.
