Hi Kevin,
same pb.
Are you missing the lockspace file as well while running on top of GlusterFS?
ovirt-ha-broker have 400% cpu and is defunct. I can't kill with -9.
Defunct process eating full four cores? I wonder how is that possible.. What are the status flags of that process when you do ps axwu?
Can you attach the log files please?

Hi,
Isn't this file created when hosted engine is started?
The file is created by the setup script. If it got lost then there was probably something bad happening in your NFS or Gluster storage.
Or how can I create this file manually?
I can give you experimental treatment for this. We do not have any official way as this is something that should not ever happen :)
!! But before you do that make sure you do not have any nodes running properly. This will destroy and reinitialize the lockspace database for the whole hosted-engine environment (which you apparently lack, but..). !!
You have to create the ha_agent/hosted-engine.lockspace file with the expected size (1MB) and then tell sanlock to initialize it as a lockspace using:
# python
> import sanlock > sanlock.write_lockspace(lockspace="hosted-engine", ... path="/rhev/data-center/mnt/<nfs>/<hosted engine storage domain>/ha_agent/hosted-engine.lockspace", ... offset=0) >
Then try starting the services (both broker and agent) again.

The errors seem to indicate that you somehow lost the lockspace file.
True :) Isn't this file created when hosted engine is started? Or how can I create this file manually?
