Re: OST Network suite is failing on "OSError: [Errno 28] No space left on device"

It's not a space issue. Other suites ran on that slave after your suite successfully. I think that the problem is the setting for max semaphores, though I don't know what you're doing to reach that limit. [dbelenky@ovirt-srv18 ~]$ ipcs -ls ------ Semaphore Limits -------- max number of arrays = 128 max semaphores per array = 250 max semaphores system wide = 32000 max ops per semop call = 32 semaphore max value = 32767 On Sun, Mar 18, 2018 at 10:31 AM, Edward Haas <ehaas(a)redhat.com&gt; wrote: > http://jenkins.ovirt.org/job/ovirt-system-tests_network-suite-master/ > > On Sun, Mar 18, 2018 at 10:24 AM, Daniel Belenky <dbelenky(a)redhat.com&gt; > wrote: > >> Hi Edi, >> >> Are there any logs? where you're running the suite? may I have a link? >> >> On Sun, Mar 18, 2018 at 8:20 AM, Edward Haas <ehaas(a)redhat.com&gt; wrote: >> >>> Good morning, >>> >>> We are running in the OST network suite a test module with Ansible and >>> it started failing during the weekend on "OSError: [Errno 28] No space left >>> on device" when attempting to take a lock in the mutiprocessing python >>> module. >>> >>> It smells like a slave resource problem, could someone help investigate >>> this? >>> >>> Thanks, >>> Edy. >>> >>> =================================== FAILURES =================================== >>> ______________________ test_ovn_provider_create_scenario _______________________ >>> >>> os_client_config = None >>> >>> def test_ovn_provider_create_scenario(os_client_config): >>> > _test_ovn_provider('create_scenario.yml') >>> >>> network-suite-master/tests/test_ovn_provider.py:68: >>> _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ >>> network-suite-master/tests/test_ovn_provider.py:78: in _test_ovn_provider >>> playbook.run() >>> network-suite-master/lib/ansiblelib.py:127: in run >>> self._run_playbook_executor() >>> network-suite-master/lib/ansiblelib.py:138: in _run_playbook_executor >>> pbex = PlaybookExecutor(**self._pbex_args) >>> /usr/lib/python2.7/site-packages/ansible/executor/playbook_executor.py:60: in __init__ >>> self._tqm = TaskQueueManager(inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=self.passwords) >>> /usr/lib/python2.7/site-packages/ansible/executor/task_queue_manager.py:104: in __init__ >>> self._final_q = multiprocessing.Queue() >>> /usr/lib64/python2.7/multiprocessing/__init__.py:218: in Queue >>> return Queue(maxsize) >>> /usr/lib64/python2.7/multiprocessing/queues.py:63: in __init__ >>> self._rlock = Lock() >>> /usr/lib64/python2.7/multiprocessing/synchronize.py:147: in __init__ >>> SemLock.__init__(self, SEMAPHORE, 1, 1) >>> _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ >>> >>> self = <Lock(owner=unknown)>, kind = 1, value = 1, maxvalue = 1 >>> >>> def __init__(self, kind, value, maxvalue): >>> > sl = self._semlock = _multiprocessing.SemLock(kind, value, maxvalue) >>> E OSError: [Errno 28] No space left on device >>> >>> /usr/lib64/python2.7/multiprocessing/synchronize.py:75: OSError >>> >>> >> >> >> -- >> >> DANIEL BELENKY >> >> RHV DEVOPS >> > > -- DANIEL BELENKY RHV DEVOPS
