Re: [ovirt-users] Diagnosing Migration Error

Hi Martin, Thanks, I checked that log and found the error " AttributeError: 'SourceThread' object has no attribute '_destServer'" which from what I see from my googling was supposedly fixed... I'm running vdsm-4.17.23-0.el7.centos.noarch which I believe is the latest. The full error is: Thread-2789::DEBUG::2016-03-18 14:47:04,200::blockSD::422::Storage.Misc.excCmd::(getReadDelay) /usr/bin/taskset --cpu-list 0-23 /usr/bin/dd if=/dev/383a1e7d-8b86-4a50-8bc3-e4374c57a3e5/metadata iflag=direct of=/dev/null bs=4096 count=1 (cwd None) Thread-2789::DEBUG::2016-03-18 14:47:04,211::blockSD::422::Storage.Misc.excCmd::(getReadDelay) SUCCESS: <err> = '1+0 records in\n1+0 records out\n4096 bytes (4.1 kB) copied, 0.000377289 s, 10.9 MB/s\n'; <rc> = 0 mailbox.SPMMonitor::DEBUG::2016-03-18 14:47:04,999::storage_mailbox::735::Storage.Misc.excCmd::(_checkForMail) /usr/bin/taskset --cpu-list 0-23 dd if=/rhev/data-center/00000001-0001-0001-0001-0000000002e9/mastersd/dom_md/inbox iflag=direct,fullblock count=1 bs=1024000 (cwd None) mailbox.SPMMonitor::DEBUG::2016-03-18 14:47:05,015::storage_mailbox::735::Storage.Misc.excCmd::(_checkForMail) SUCCESS: <err> = '1+0 records in\n1+0 records out\n1024000 bytes (1.0 MB) copied, 0.0057206 s, 179 MB/s\n'; <rc> = 0 jsonrpc.Executor/0::DEBUG::2016-03-18 14:47:06,551::__init__::503::jsonrpc.JsonRpcServer::(_serveRequest) Calling 'VM.migrate' in bridge with {u'params': {u'tunneled': u'false', u'autoConverge': u'false', u'src': u'ovirt-01.virt.roblib.upei.ca', u'dst': u'ovirt-02.virt.roblib.upei.ca:54321', u'vmId': u'2be4938e-f4a3-4322-bae3-8a9628b81835', u'abortOnError': u'true', u'compressed': u'false', u'method': u'online'}, u'vmID': u'2be4938e-f4a3-4322-bae3-8a9628b81835'} jsonrpc.Executor/0::DEBUG::2016-03-18 14:47:06,552::API::546::vds::(migrate) {u'tunneled': u'false', u'autoConverge': u'false', u'src': u'ovirt-01.virt.roblib.upei.ca', u'dst': u'ovirt-02.virt.roblib.upei.ca:54321', u'vmId': u'2be4938e-f4a3-4322-bae3-8a9628b81835', u'abortOnError': u'true', u'compressed': u'false', u'method': u'online'} jsonrpc.Executor/0::DEBUG::2016-03-18 14:47:06,555::__init__::206::jsonrpc.Notification::(emit) Sending event {"params": {"2be4938e-f4a3-4322-bae3-8a9628b81835": {"status": "Migration Source"}, "notify_time": 4311153220}, "jsonrpc": "2.0", "method": "|virt|VM_status|2be4938e-f4a3-4322-bae3-8a9628b81835"} jsonrpc.Executor/0::DEBUG::2016-03-18 14:47:06,555::__init__::533::jsonrpc.JsonRpcServer::(_serveRequest) Return 'VM.migrate' in bridge with True Thread-41096::ERROR::2016-03-18 14:47:06,559::migration::208::virt.vm::(_recover) vmId=`2be4938e-f4a3-4322-bae3-8a9628b81835`::[Errno -2] Name or service not known Thread-41096::ERROR::2016-03-18 14:47:06,559::migration::213::virt.vm::(_recover) vmId=`2be4938e-f4a3-4322-bae3-8a9628b81835`::Failed to destroy remote VM Traceback (most recent call last): File "/usr/share/vdsm/virt/migration.py", line 211, in _recover self._destServer.destroy(self._vm.id) AttributeError: 'SourceThread' object has no attribute '_destServer' Thread-41096::DEBUG::2016-03-18 14:47:06,560::__init__::206::jsonrpc.Notification::(emit) Sending event {"params": {"2be4938e-f4a3-4322-bae3-8a9628b81835": {"status": "Migration Source"}, "notify_time": 4311153220}, "jsonrpc": "2.0", "method": "|virt|VM_status|2be4938e-f4a3-4322-bae3-8a9628b81835"} Thread-41096::ERROR::2016-03-18 14:47:06,560::migration::309::virt.vm::(run) vmId=`2be4938e-f4a3-4322-bae3-8a9628b81835`::Failed to migrate Traceback (most recent call last): File "/usr/share/vdsm/virt/migration.py", line 278, in run self._setupVdsConnection() File "/usr/share/vdsm/virt/migration.py", line 143, in _setupVdsConnection client = self._createClient(port) File "/usr/share/vdsm/virt/migration.py", line 130, in _createClient self.remoteHost, int(port), sslctx) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 1269, in create_connected_socket sock.connect((host, port)) File "/usr/lib64/python2.7/site-packages/M2Crypto/SSL/Connection.py", line 181, in connect self.socket.connect(addr) File "/usr/lib64/python2.7/socket.py", line 224, in meth return getattr(self._sock,name)(*args) gaierror: [Errno -2] Name or service not known
