Hi,

Came into the office with an issue with my ovirt setup this morning.  On one 
of my hosts the / partition was completely full causing the host to go into 
an unknown state.  I was able to clear out some space for the time being and 
attempting to recover my that host.  VM's are still running and responding 
on the host.

I am using Gluster volumes in my configuration, and had to restart gluster 
service on that host.  I also restarted the ovirt-ha-agent service.

I am seeing this entry in my agent.log every two seconds:

MainThread::INFO::2017-02-02 
09:11:19,606::util::214::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(connect_vdsm_json_rpc)
 
Waiting for VDSM hardware info

In my vdsm.log i am seeing this

I attempt to move my service into maintenance mode, but it is unable to 
migrate any of my vm's on that host over to another host.  Is there away to 
get my host running again with out reboot or to migrate my VM's via CLI so i 
can restart my host.

Thanks
