[ovirt-users] Re: Host NonResponsive after migration to oVirt 4.4

Tue, 10 Nov 2020 04:47:00 -0800

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:

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:


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
