Re: [Users] hosted engine issues

Hi, I have some issues with hosted engine (oVirt 3.4 prerelease repo on CentOS 6.5). My setups is the following: 2 hosts (will be 4 in the future) with 4 GlusterFS shares: - engine (for hosted engine) - iso (for ISO domain) - ovirt (oVirt storage domain) I had a split-brain situation today (after rebooting both nodes) on hosted-engine.lockspace file on engine GlusterFS volume which I resolved.

hosted engine used engine share via NFS (TCP) as glusterfs isn't supported for oVirt hosted engine, yet. I'll switch to GlusterFS as soon as oVirt will support it (I hope this will be soon as RHEV 3.3 is already supporting GlusterFS for hosted engine). First of all ovirt-ha-agent fails to start on both nodes: # service ovirt-ha-agent start Starting ovirt-ha-agent: [ OK ] # service ovirt-ha-agent status ovirt-ha-agent dead but subsys locked MainThread::INFO::2014-03-03 11:20:39,539::agent::52::ovirt_hosted_engine_ha.agent.agent.Agent::(run) ovirt-hosted-engine-ha agent 1.1.0 started MainThread::INFO::2014-03-03 11:20:39,590::hosted_engine::223::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_get_hostname) Found certificate common name: 10.0.200.101 MainThread::CRITICAL::2014-03-03 11:20:39,590::agent::103::ovirt_hosted_engine_ha.agent.agent.Agent::(run) Could not start ha-agent Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/agent/agent.py", line 97, in run self._run_agent() File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/agent/agent.py", line 154, in _run_agent hosted_engine.HostedEngine(self.shutdown_requested).start_monitoring() File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 152, in __init__ "STOP_VM": self._stop_engine_vm File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/agent/state_machine.py", line 56, in __init__ logger, actions) File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/lib/fsm/machine.py", line 93, in __init__ self._logger = FSMLoggerAdapter(logger, self) File "/usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/lib/fsm/machine.py", line 16, in __init__ super(FSMLoggerAdapter, self).__init__(logger, None) TypeError: super() argument 1 must be type, not classobj If I want to start my hosted engine, I receive the following error in vdsm logs, which makes absolutly no sense to me, as there is plenty of disk space available: Thread-62::DEBUG::2014-03-03 11:24:46,282::libvirtconnection::124::root::(wrapper) Unknown libvirterror: ecode: 38 edom: 42 level: 2 message: Failed to acquire lock: No space left on device

Thanks a lot. Btw, I had some issues during installation which I will explain in separate emails.
