d hosted engine
Hi Moacir,
First switch off all VMs.
Second you need to declare hosts maintenance mode, don't start with SRM (of=
course if you are able use the ovirt-engine), it will ask you to shutdown =
the glusterfs on a machine.
Third if all machines are in maintenance mode, you can start shutting down =
them.
If you have hosted engine setup follow this [1]
Cheers
Erekle
