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
