I think the missing part here is stopping the SPM (if running on this
host), and disconnecting
from storage.
Yes, it is of course the SPM, because this is a single node HCI environment
Both are done when you put a host to maintenance, but in hosted
engine
environment this
is not possible from engine since engine runs on the storage you want
to disconnect.
In fact. From here my question and doubts

I think there is an ansible script to do what you need, or some other
script.
Simone, do you know where the clean shutdown script for HCI env?
Nir
Let's say that in a "standard production" HCI environment, with
suppose 3
nodes, you have a planned maintenance and you have to shutdown all three
nodes: the same applies when you have to shutdown the last node, but I
imagine you have also to do something with gluster when you shutdown the
second node because you have not quorum anymore, correct?
Thanks,
Gianluca
