Host NonResponsive after migration to oVirt 4.4
Hi I am looking for help after my oVirt upgrade failed. I have upgraded from ovirt 4.3 to 4.4 following the instructions here: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 <https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3> It's a single-host (standalone engine) test environment. I wiped CentOS 7 and reinstalled a fresh CentOS 8. I installed the oVirt 4.4 repo and all the necessary software packets. I used `engine-backup --mode=restore --file=/tmp/ovirt-engine-pre-upgrade.backup --provision-all-databases` from a backup file I created before I started the upgrade. After the restore, I ran `engine-setup`. I did not get any errors during any of these steps on the console. So the upgrade could be considered successful from that perspective. After the upgrade, I login to the ovirt admin portal, and I try to "Activate" my host (was set to "Maintenance" mode before upgrade). The Activation fails with error "NonResponsive" in the GUI. Under the "bell" icon, I find the Event "Host nuc1.feric.ch is non responsive.” In /var/log/ovirt-engine/engine.log, I find the following error: ``` 2020-11-09 23:12:21,080+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-47) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = nuc1.feric.ch, VdsIdAndVdsVDSCommandParametersBase:{hostId='d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb', vds=‘Host[nuc1.feric.h,d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb]'})' execution failed: java.net.ConnectException: Connection refused ``` `systemctl status ovirt-engine` shows that the engine is running. I am able to reboot the host from the oVirt GUI directly. Does anyone have an idea how to proceed? Many thanks Toni
Hello, Can you share vdsm logs you can find at /var/log/vdsm/vdsm.log. I guess this might be a vdsm issue between an engine and host. also check in ui whether a nic is attached to the host after upgrade. On Tue, Nov 10, 2020 at 5:18 PM tferic@swissonline.ch <tferic@swissonline.ch> wrote:

Hello Yedidyah Many thanks for clarification. If I wanted to convert my all-in-one installation to a "supported" one (on a single box), would I have to migrate my engine into a self-hosted VM? What would be the most common way to conform? I was able to fix my problem by: * uninstalling oVirt * yum update * installing oVirt 4.4.3 * installing cockpit-ovirt-dashboard (which installs vdsm etc. as dependency) * modifying the engine-backup script (don't bail out on restore if version<4.3.10) * Restore engine from backup file * engine-setup * Reinstall host from oVirt UI Many thanks Toni Feric On 10.11.20 14:22, Yedidyah Bar David wrote:

Basically one of two approaches, depending on your needs: 1. For production, I think most people use hyper-converged hosted-engine (meaning, local gluster storage and engine its a self-hosted vm). If you do not want to use gluster, some people also reported using local NFS/iSCSI, although at least NFS used to be considered risky (due to locking issues). Most people, though, consider this overkill - you don't enjoy many of its features, but it's more complex than e.g. virt-manager. 2. For learning/development/testing, I think most people use virt-manager, or virsh (perhaps wrapped in custom scripts) or something similar, to create separate VMs, and then use these as machines for oVirt - can be a host (with nested-kvm) on one, standalone engine or hosted-engine host on another, storage on another (or on the physical machine) - depending on what you want to do. If you feel like combining both - meaning, (2.), but using oVirt also for the physical machine - that's just fine too.
I was able to fix my problem by:
uninstalling oVirt yum update installing oVirt 4.4.3 installing cockpit-ovirt-dashboard (which installs vdsm etc. as dependency) modifying the engine-backup script (don't bail out on restore if version<4.3.10) Restore engine from backup file engine-setup Reinstall host from oVirt UI
Seems reasonable. Thanks for the update! Best regards,
Many thanks

Hello,
Looks like you are checking this directory in the engine. You will get this in the host. Also check vdsm service is running or not using systemctl status vdsmd

Hello Ritesh
I can see the NIC attached to the host in the UI. However, I don’t have a directory /var/log/vdsm. I am sharing the filetree of my /var/log in the separately attached text file:
Thanks, Toni

Hello,
Can you share vdsm logs you can find at /var/log/vdsm/vdsm.log.
I guess this might be a vdsm issue between an engine and host. also check in ui whether a nic is attached to the host after upgrade.

Hi
I am looking for help after my oVirt upgrade failed.
I have upgraded from ovirt 4.3 to 4.4 following the instructions here:
https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3
It's a single-host (standalone engine) test environment. I wiped CentOS 7 and reinstalled a fresh CentOS 8. I installed the oVirt 4.4 repo and all the necessary software packets.
I used `engine-backup --mode=restore --file=/tmp/ovirt-engine-pre-upgrade.backup --provision-all-databases` from a backup file I created before I started the upgrade. After the restore, I ran `engine-setup`.
I did not get any errors during any of these steps on the console. So the upgrade could be considered successful from that perspective.
After the upgrade, I login to the ovirt admin portal, and I try to "Activate" my host (was set to "Maintenance" mode before upgrade).
Please try 'Reinstall'.
This should install vdsm for you, among many other things.
Best regards,
The Activation fails with error "NonResponsive" in the GUI. Under the "bell" icon, I find the Event "Host nuc1.feric.ch is non responsive.”
In /var/log/ovirt-engine/engine.log, I find the following error: ``` 2020-11-09 23:12:21,080+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-47) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = nuc1.feric.ch, VdsIdAndVdsVDSCommandParametersBase:{hostId='d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb', vds=‘Host[nuc1.feric.h,d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb]'})' execution failed: java.net.ConnectException: Connection refused ```
`systemctl status ovirt-engine` shows that the engine is running. I am able to reboot the host from the oVirt GUI directly.
Does anyone have an idea how to proceed?
