Hello, I have a 2 node replicated glusterfs storage cluster configured that shows up under storage. I need to take both of these glusterfs nodes down to perform some hardware upgrades. I'm wondering if I need to put this storage into maintenance mode or if putting each host into maintenance mode is good enough? The reason I'm asking is the last time I took one of these glusterfs servers down leaving the other up we ended up in a split brain state that I'm trying to avoid. Once the hardware upgrade has been performed I will be adding a 3rd brick/node to this config which should make things a bit happier.
