Hi all,

I had a setup with ovirt 4.2.0 which at some point the engine stopped responding, due to some split brain issues.

Since was not able to resolve the split brain, I proceeded to redeploy the engine.

The steps I followed:

1. upgrade servers (yum update)

2. ran ovirt-hosted-engine-cleanup

3. deployed engine (now 4.2.7)

The deploy was successful and was able to add a new data domain.

The issue is that at this point I would expect the engine storage domain and VM to be automatically imported, but it is not. At HA agent logs at the server I see:

MainThread::INFO::2018-11-17 12:55:51,856::states::444::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(consume) Engine vm running on localhost

While at engine.log of engine VM I see:

Sth is causing engine not not getting imported.

Tried to run hosted-engine –reinitialize-lockspace, since I was getting some lockspace errors, but no change.

Any idea what could be causing this?

I am left with little time due to the site being production. Any idea is appreciated.

Thanx,

Alex

In step 3 how did you deploy engine?

I had the same problem some days ago and was due to a bug in using  command line and excluding ansible (option --no-ansible)

I solved redeploying using the default that is with ansible

I deployed with --no-ansible flag since the ansible way was giving me an error (sth with localhost). I can try ansible to check what was the error.

The error I am getting when trying to deploy with ansible is the following:

How Can I overcome this? I recall I've seen this on past attempts also and was able to proceed only with the traditional python (--no-ansible) way.

I was able to overcome this by amending the /etc/hosts file at the server. It had some erroneous entries.

The deployment was able to proceed and engine is up though it gave only at the end the following error:

The engine is up and I can SSH into it. Though when I try to login through GUI I get " The redirection URI for client is not registered ", even though I have set its IP address in SSO_ALTERNATE_ENGINE_FQDNS through a config file.   What could be the issue now? Thanx

HIH,
