Hello, following this reference guide: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_no... 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:

Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned Correct?

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?us... 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

[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

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?

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?

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

I was playing around with a 3 node setup. This was on 4.3 based on FC28. In the Cockpit UI, after completing the 1st stage of the hyperconverged setup, I saw this (see pic)

Yes, Gianluca, that is correct. First, I had to configure a 3 node cluster. There was no other way to get to the setup page shown in my screenshot. 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.

Instead, based on Sahina answer, the single node HCI setup is supposed to work ootb without previously configuring anything related to Gluster, correct?

Thanks for the update, Gobinda. Looking forward to the fix.
