Hello all, Later this month, I will have to bring down, patch, and reboot all nodes in our cluster for maintenance. The two options available to set nodes into a maintenance mode seem to be either: 1) creating a system-wide reservation, or 2) setting all nodes into a DRAIN state.
I'm not sure it really matters either way, but is there any preference one way or the other? Any gotchas I should be aware of? Warmest regards, Jason -- *Jason L.
