Hello ovirt users,

I have 4 hosts with a distributed replicated 2x2 GlusterFS storage. (oVirt3.5/CentOS7)

When I reboot a host (in maintenance mode and not my SPM host) my Data Center becomes "Non Responsive", my storage becomes red and inactive, and many VMs become "paused due to unknown storage error". The same happens if I administratively set ovirtmgmt network down (to a host in maintenance mode and not my SPM host) with ifconfig ovirtmgmt down. I know that management network (ovirtmgmt) is required by default and is part of oVirt monitoring process but is there anything I can do in order to reboot a host without causing this mess?
