24 Feb '21

Hi, I've one server ovirt-engine. I've trois nodes glusterfs on this ovirt-engine. Ex: ovirt-engine : ovirt-node1, ovirt-node2 and ovirt-node3. Now, I want add ovirt-node4. I tried with "Deploying oVirt and Gluster Hyperconverged". But it propose only trois nodes. Could you help me, please ? Best regard, Anne Garcia

oVirt Ansible cluster deployment
by Jeremey Wise 24 Feb '21

24 Feb '21

I am trying to eat own dog food. Infrastructure as code... So.. I have taken three physical servers. Setup all the base packages, set NICs, NTP, DNS, collected disk UUIDs etc.. The servers are prepped. And one server has cockpit and ovirt-engine installed... and service started. ############################# --- # This task takes nodes prepaired and deploys cockpit, ovirt deployment and scripts cluster initilization. ONLY RUN THIS ON FIRST NODE OF CLUSTER # v0.001 20210222 # file: /roles/task_hci_setup.yml # Documentation # Overview: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_H… - name: Check if rpm ovirt-release44 is already installed yum: list: ovirt-release44 register: yum_list - name: Conditionally do next thing debug: msg: "ovirt-release44 Not installed" when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 # Add oVirt Repo manual. - name: Download oVirt Repo RPM get_url: url: https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm dest: ~/ovirt-release44.rpm mode: '0440' when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 - name: Install Python3 as this is needed for oVirt. yum: name: - python3 state: latest become: true - name: For some reason install of oVirt Repo fails as package so have to run as shell command: "rpm -ivh ~/ovirt-release44.rpm" when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 - name: With new oVirt repo.. install rest of HCI dependancies yum: name: - cockpit-ovirt-dashboard - vdsm-gluster - ovirt-host - ovirt-ansible-roles - ovirt-ansible-infra state: latest become: true # Set variable for first node in cluster list to set as ignition master - name: Only on first node thor deploy ovirt-engine-appliance yum: name: - ovirt-engine-appliance state: latest become: true when: "'{{ hci_ignition_node }}' in inventory_hostname" # on local ansible host install galaxy modules # Broken: I need a means to check if installed.

Which is ... what I would do in the wizard... ... but "step away from the mouse". # Ansible section: from bastion node (laptop windows 10 WSL with ansible and galaxy installed # 1) build playbook from my site variables... based on some ovirt master sharing template of what that UI builds # 2) push the playbook that installs ansible on the first node. Install ansible as a first node... Run ansible playbook from customized template file # 3) Create vlans. # 4) Setup new VM gluster shared volume from three other disk # 5) Push a template VM into cluster, attached to new VLAN and attached to new volume #6) Deploy VM from this template #7) Drink a cold beer ############################### Question: 1) Can you do ansible deployment from "bastion host" or does the ansible have to run on the node that is installed with the "ovirt-engine". If so.. how do you collect feedback etc.. 2) I assume there is a template. Maybe it is published but I could not find it. That I replace (or match) variables of my site that fill in that file. 3) I installed galaxy oVirt.ovirt-ansible-roles but.. how do I know it is deployed on my bastion host? I poked around in the ansible folder.. not seeing anything. And I assume this only is of help POST the above seven steps being done. But maybe this has deployment components and I am missing documents. Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

Did you install ovirt-guest-tools on the VM from the iso available at your engine vm package? Did the related service start in WIndows 10 OS? You didn't reply why you are forced to use so an "old" oVirt version: it is not old in absolute, but oVirt is rapidly evolving and you should stay at maximum behind one version. So if the latest is 4.3, stay no behind 4.2. Now, with 4.4 out since many months, stay no behind 4.3 at least... This way you get more correct help because more guys are on latest versions, that got many enhancements and many bug fixes (eg with snapshot management, illegal disks state some time, and so on) Gianluca

Invalid status on Data Center Default. Setting status to Non Responsive.
by Jelte Veldstra | Order2Cash 23 Feb '21

23 Feb '21

All, We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape. When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log: 2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive. Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log. The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to? How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it. Regards, Jelte

Hi Joseph, Somehow I missed your email. I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed. Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊 For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again. Too many CI/CD deployment failures, to leave the engine process fighting for resources. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

There are different parameters around memory - are you sure you change the correct one(s)? Also adding Arik. Arik - please see the history of this thread. It might be an issue in the engine, or in hosted-engine HA, or both - not sure. > But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version? No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it reproduces, file a bug and attach all relevant logs (including engine, vdsm, hosted-engine-ha).

Re: oVirt Engine increase RAM and CPU

Hi Marko, I have also had this problem on an oVirt 4.3 install - I could never fix it and have not tried to upgrade to 4.4 yet - my workaround for now (as you have deduced) is to just 'up' it while running so its hotswapped in - annoying, but I think the best way around this without upgrade would be to re-deploy the hosted engine defining the new resources using an engine-backup - but again this is just as scary as in-place upgrade lest you lock yourself out from your other running VMs in a production environment. I plan to do it - I just need some time to set it up in a lab so I know what to expect.

Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384. I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated. Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change. Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384. Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.
