Dafna,
in 'verify_add_hosts' we specifically wait for single host to be up with a
timeout:
144 up_hosts = hosts_service.list(search='datacenter={} AND
status=up'.format(DC_NAME))
145 if len(up_hosts):
146 return True
The log files say, that it took ~50 secs for one of the hosts to be up
(seems reasonable) and no timeout is being reported.
Just after running 'verify_add_hosts', we run
'add_master_storage_domain',
which calls '_hosts_in_dc' function.
That function does the exact same check, but it fails:
113 hosts = hosts_service.list(search='datacenter={} AND
status=up'.format(dc_name))
114 if hosts:
115 if random_host:
116 return random.choice(hosts)
I don't think it is relevant to our current failure; but I consider
random_host=True as a bad practice. As if we do not have enough moving
parts, we are adding intentional randomness. Reproducibility is far more
important than coverage - particularly for a shared system test like OST.
117 else:
118 return sorted(hosts, key=lambda host: host.name)
119 raise RuntimeError('Could not find hosts that are up in DC %s' %
dc_name)
I'm also not able to reproduce this issue locally on my server. The
investigation continues...
I think that it would be fair to take the filtering by host state out of
Engine and into the test, where we can easily log the current status of
each host. Then we'd have better understanding on the next failure.

Hi,
sure, I'm on it - it's weird though, I did ran 4.3 basic suite for this
patch manually and everything was ok.

Hi,
We are failing branch 4.3 for test: 002_bootstrap.add_master_storage_domain
It seems that in one of the hosts, the vdsm is not starting
there is nothing in vdsm.log or in supervdsm.log
CQ identified this patch as the suspected root cause:
https://gerrit.ovirt.org/#/c/98748/ - vdsm: client: Add support for flow

Milan, Marcin, can you please have a look?
full logs:
http://jenkins.ovirt.org/job/ovirt-4.3_change-queue-tester/326/artifact/b...
the only error I can see is about host not being up (makes sense as vdsm
is not running)
