Everytime I try to change assigned Logical networks (add ip addresses, assign a logical network, etc) the bond0 interface winds up going down. I have to do a ifup bond0 from the console, and the engine reconnects. After a lot of digging, I think this is the offending command, but I don't know how to read it or next troubleshooting steps. Anyone want to point me in the right direction? Thanks! 2018-07-28 18:07:36,661-0500 WARN (vdsm.Scheduler) [Executor] Worker blocked: <Worker name=jsonrpc/6 running <Task <JsonRpcTask {'params': {u'connectionParams': [{u'netIfaceName': u'bond0.3001', u'id': u'0808bc71-b5f7-4886-9dc8-e21b0d2abf14', u'connection': u'192.168.200.81', u'iqn': u'iqn.2002-10.com.infortrend:raid.uid577981.001', u'user': u'', u'tpgt': u'1', u'ifaceName': u'bond0.3001', u'password': '********', u'port': u'3260'}, {u'netIfaceName': u'bond0.3002', u'id': u'77c7e9dd-cd46-48be-ade1-06645772c405', u'connection': u'192.168.200.81', u'iqn': u'iqn.2002-10.com.infortrend:raid.uid577981.001', u'user': u'', u'tpgt': u'1', u'ifaceName': u'bond0.3002', u'password': '********', u'port': u'3260'}], u'storagepoolID': u'2cde92be-7b43-11e8-b08d-00505690367f', u'domainType': 3}, 'jsonrpc': '2.0', 'method': u'StoragePool.connectStorageServer', 'id': u'9a414389-2b42-4a20-b59c-c3bc9d19c7b4'} at 0x7f29980cdcd0> timeout=60, duration=60 at 0x7f29980cdfd0> task#=4 at 0x7f299837af10>, traceback: File: "/usr/lib64/python2.7/threading.py", line 785, in __bootstrap self.__bootstrap_inner() File: "/usr/lib64/python2.7/threading.py", line 812, in __bootstrap_inner self.run() File: "/usr/lib64/python2.7/threading.py", line 765, in run self.__target(*self.__args, **self.__kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/common/concurrent.py", line 194, in run ret = func(*args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 301, in _run self._execute_task() File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 315, in _execute_task task() File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 391, in __call__ self._callable() File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 523, in __call__ self._handler(self._ctx, self._req) File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 566, in _serveRequest response = self._handle_request(req, ctx) File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 606, in _handle_request res = method(**params) File: "/usr/lib/python2.7/site-packages/vdsm/rpc/Bridge.py", line 197, in _dynamicMethod result = fn(*methodArgs) File: "/usr/lib/python2.7/site-packages/vdsm/API.py", line 1070, in connectStorageServer connectionParams) File: "/usr/lib/python2.7/site-packages/vdsm/storage/dispatcher.py", line 73, in wrapper result = ctask.prepare(func, *args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 108, in wrapper return m(self, *a, **kw) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 1179, in prepare result = self._run(func, *args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File: "<string>", line 2, in connectStorageServer File: "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2395, in connectStorageServer conObj.connect() File: "/usr/lib/python2.7/site-packages/vdsm/storage/storageServer.py", line 487, in connect iscsi.addIscsiNode(self._iface, self._target, self._cred) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsi.py", line 217, in addIscsiNode iscsiadm.node_login(iface.name, target.address, target.iqn) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsiadm.py", line 327, in node_login portal, "-l"]) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsiadm.py", line 122, in _runCmd return misc.execCmd(cmd, printable=printCmd, sudo=True, sync=sync) File: "/usr/lib/python2.7/site-packages/vdsm/common/commands.py", line 80, in execCmd (out, err) = p.communicate(data) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 924, in communicate stdout, stderr = self._communicate(input, endtime, timeout) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 1706, in _communicate orig_timeout) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 1779, in _communicate_with_poll ready = poller.poll(self._remaining_time(endtime)) (executor:363)
