In a DHCP failover association what happens when one member runs out on IPs in its pool. I mean if the DHCP range is 192.168.1.1-192.168.1.100 and the split is 50/50, what happens if member1 leases all the IP addresses in its pool {192.168.1.1-192.168.1.50}?

Periodically the members in the DHCP FO pair will rebalance the “load” so that each will be roughly 50/50. If server A starts running out, it’ll ask server B to swap some addresses (taking some free ones and assigning some used ones). There’s a detailed algorithm in place specifically to address these scenarios.

I recommend looking through some of the support KB articles. You’ll find some interesting info if you need to get deeper into the weeds on this.
