Hello, following this reference guide:

https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node_...

after having run with success the gdeploy based gluster setup, there is

Setting up Hosted Engine Use the Ansible based installation flow of Hosted Engine to set up oVirt within a virtual machine. The storage details should be provided as type: glusterfs and connection path as: <hostname>:/engine (Replace hostname with address of host on which installation is carried out)

What does exactly mean "Use the Ansible based instalation" ? Does it mean using cockpit web ui? In this casae I suppose I have to choose:

It's simply the new node zero deployment flow which is now the default one from cockpit and also from CLI.

Thanks for the answer, Simone, but I have not understood. I used ovirt-node-ng-installer-ovirt-4.2-2018082006.iso to install the OS host node. Does this resemble what you call "new node zero deployment flow"? When connecting to cockpit and selecting hosted engine, I get this screen:

https://drive.google.com/file/d/1aPLCm0KW5IIp6f7xr41cysckPkFgdHtJ/view?usp=s...

what to choose and if any particular setup needs? As I wrote, the command "gdeploy -c gdeploy.conf" completed without errors on the host and now I have the 3 (small, only to test the workflow for now) gluster volumes running

Now you can simply continue with "Hosted Engine" button in cockpit. You could also skip the manual execution of gdeploy from CLI and do everything from cockpit with the "Hyperconverged" button but now you already did it.

[root@hcinode1 ~]# df -h | grep gluster /dev/mapper/gluster_vg1-engine_lv 60G 33M 60G 1% /gluster_bricks/engine /dev/mapper/gluster_vg1-lv_vmdisks 20G 34M 20G 1% /gluster_bricks/vmstore /dev/mapper/gluster_vg1-lv_datadisks 25G 34M 25G 1% /gluster_bricks/data [root@hcinode1 ~]#

[root@hcinode1 ~]# gluster volume list data engine vmstore [root@hcinode1 ~]#

Thanks, Gianluca

Thanks for your time, Simone. The installation went ok until the problem below due to my engine gluster volume too small (I set up 60Gb for it and it didn't fit for some MBs..). I got:

[ INFO ] TASK [Check storage domain free space] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error: the target storage domain contains only 59.0GiB of available space while a minimum of 60.0GiB is required If you wish to use the current target storage domain by extending it, make sure it contains nothing before adding it."}

Then I scratched (it is a small nested test and so I simply discarded the changes) and updated gdeploy.conf to accomodate 65Gb for the engine gluster volume and all went pretty smooth then. I also noticed that the engine VM and its storage domain is already visible in web admin portal, so there is no immediate need to add another data domain and get hosted engine imported as before, correct?

Yes, as expected with the new flow. Theoretically you can just end with a single SD for hosted-engine and regular VMs but keep them distinct is highly recommended for maitenability.

I'm up and running and I'm going to scratch again and test your suggestion to bypass also the gdeploy.conf step and go all with gui. In fact I notice that when configuring storage there is a note saying " Please note that only replica 1 and replica 3 volumes are supported. "

.. I'll let you know if it goes ok the all gui setup.

In the mean time one further question: it seems that the cluster configured has not the "gluster service" checkbox enabled, so I think it is for that reason that I don't see any gluster related configuration information inside the web admin portal.... Is this expected with this approach? Is something different expected when trying instead the full gui approach? Will the web admin portal aware of the gluster config in that case?

Yes, in that case hosted-engine-setup will be aware of the hyperconverged configuration and it will automatically configure the cluster for the gluster server adding also the two additional hosts.

Also because a further step I would like to try is to extend this initial setup to a 3-node based gluster one...

Thanks again, Gianluca

Simone,

https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node_...

For single node hyperconverged, are you saying we can do the setup 100% from the Cockpit gui without the gdeploy config file??

I'm just trying it, after reverting to snapshot of my VM that should work as single host HCI node. So now no gluster configuration in place and second disk free to be configured by gui. I select now the right box of Hosted Engine Setup page, the one with " Hyperconverged Configure gluster storage and oVirt hosted engine " Then select "Start" button. In the new page I put the ip of second network adapter of host1 that I plan to use for gluster storage, but then I receive these warnings about host2 and host3, so that I cannot go ahead... https://drive.google.com/file/d/1mO02Lu57tHlc6O24H2uTv9JSn1hyTbub/view?usp=s... What to do? Thanks, Gianluca

What to do?

Can you please open a bug against the cockpit HE wizard for that?

We do have to https://bugzilla.redhat.com/show_bug.cgi?id=1608660 and will be available in oVirt 4.2.6

Hello, the bugzilla seems in QA, but in 4.2.6 rc3 ovirt node iso (ovirt-node-ng-installer-ovirt-4.2-pre-2018082812.iso) nothing changes: I receive "Host address cannot be empty" for host2 and host3 BTW: Femi, but in your screenshot with F28 the top message containing "An existing gluster configuration has been found." seems to indicate that actually you already configured gluster on that single host, correct? Instead, based on Sahina answer, the single node HCI setup is supposed to work ootb without previously configuring anything related to Gluster, correct? Gianluca

Hi, Single node deployment should not expect gluster configuration. But now I can see it's expecting he-answer.conf which should be available default. Anyways will fix this and let you know.

I assume when it gets fixed in 4.2.6, we will be able to get to the single node config page right off the bat.
