[ovirt-users] Data Center becomes Non Responsive when I reboot a host

[Artyom Lukianov]

Just put host to maintenance mode, if it have vms it will migrate them automatically on other host.

Subject: [ovirt-users] Data Center becomes Non Responsive when I reboot a	host

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?

Thanks,

K.
