Hi Gianluca,

yes, you are right. Now second and third host can be
directly added from UI. Before adding the second and third
host please make sure that the following steps are done for
hyperconverged setup.

1) On Hosted engine vm run the command 'engine-config -s
AllowClusterWithVirtGlusterEnabled=true'

2) Restart ovirt-engine by running the command 'service
ovirt-engine restart'

3) /Edit Cluster/>/Default/>/Enable the gluster service/.

4) Create separate storage domains for each gluster volume.
You can see that hosted_storage gets imported into the UI
automatically when one storage domain is created in the UI.

5) Add second and third host from UI.

Hope this helps

Hello,
thanks for your answer.
Basically I'm following Jason guide here for 4.0:

https://www.ovirt.org/blog/2016/08/up-and-running-with-ovirt-4-0-and-gluster-storage/



I arrived just before the second/third host deploy actions.
I verified that

1) actually seems already in place
[root@ovengine ~]# engine-config -g
AllowClusterWithVirtGlusterEnabled
AllowClusterWithVirtGlusterEnabled: true version: general
[root@ovengine ~]#

3) Already done

2) Already done after step 3)


I see that in Jason guide steps 4) and 5) are reversed.
Are they interchangeable or is that using the web admin deploy
method requires that storage domains are already set up before
adding second host?

Before adding second host, it requires hosted_storage domain to be
imported into the UI. For this to happen we need to atleast add
one domain. With out creating a storage domain you can try adding
the second host and you will be given a message to add the domain
first.

Thanks for clarifications.
It worked smoothly; all the three hosts are now up; going to test 
urther functionalities.

Fine!

In the host-deploy logs for the 3 hosts I only see for the third host 
(and for the first file of the two ones generated for first host) 
these kinds of warning:

Do I have to worry about them?

Thanks again

you could safely ignore these messages. There are some tuned profiles 
which engine tries to set on the node. If those profiles does not exist 
on the node engine throws these kind of messages.

In the past the command to give on them was

root@host3 # hosted-engine --deploy

But I also seem to remember that perhaps this has been superseded and 
possible to direct deploy now host2 and host3 from web admin gui with

Is this true in general? And in particular in my case?
