But you can control this with the boot configuration. # Fixed group sizes # # Here we boot 2 hosts at a time with a 10 second gap between each group. boot: limit: 2 wait: 10 # Percentage of hosts # # Here we boot 25% of the hosts at a time with a 2 second gap between each group. boot: limit: 25% wait: 2
