hi,
It's really not a single point of failure ? In this way i see 2
point of failure, if the hosted-engine break and if the mount server
adress break. And it's not possible to migrate the engine.
Can you
explain me why is not a point of failure for you ?

Hi,
on oVirt 3.6 we still not
support hyper convergence that means that you cannot use
the same hosts
for virtualization and for storage with gluster.
So the correct
approach is renaming your hosts to:
host 1 : "192.168.100.101
gluster1.localdomain
gluster1"
host 2 : "192.168.100.102
gluster2.localdomain
gluster2"
host 3 : "192.168.100.103
gluster3.localdomain
gluster3"
On an additional host, deploy
hosted-engine choosing the gluster host you prefer as
your entry point:
it will not be a single point of failure.
You don't really need to
use CTDB to deploy oVirt
hosted-engine.
> i don't want to use ctdb
for my hosted-engine, but when i start
hosted-engine --deploy, use
localhost:/engine or gluster.localdomain:/engine, gluster.localdomain is
configured in all servers /etc/hosts like :
> host 1 : "192.168.100.101
gluster.localdomain
gluster"
> host 2 : "192.168.100.102
gluster.localdomain
gluster"
> host 3 : "192.168.100.103
gluster.localdomain
gluster",
