In earlier versions, host maintenance did not stop gluster related services. With 3.6, when putting a host to maintenance there's an option to also stop all gluster related services. Use this option to shutdown your gluster services from oVirt. On 04/28/2016 08:32 PM, Edward Clay wrote:

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.
