What is the proper method to restart two node failover-dhcp services?

[Carlos Vicente]

This is what I remember reading on this list:

a) Bringing both servers back into sync: Move or rename the leases
file on the secondary. Restart dhcpd on the secondary.
b) Restarting after making config changes: Restart the secondary
first. When that is done, restart the primary.

Hope this helps.
