I fail to restart the quantum-server recently without any error log output.
root@controller:~# service quantum-server restart
stop: Unknown instance:
quantum-server start/running, process 3763
root@controller:~# service quantum-server restart
stop: Unknown instance:
quantum-server start/running, process 4231
I trace to the code below finally:
# remove from table unallocated vlans for any unconfigured physical
# networks
for allocs in allocations.itervalues():
for alloc in allocs:
if not alloc.allocated:
LOG.debug("removing vlan %s on physical network %s"
" from pool" %
(alloc.vlan_id, *physical_network*))
session.delete(alloc)
the local vairable *physical_network* should be *alloc.physical_network*
I suggest to add some error output to the logger
root@controller:~# quantum-server --config-file /etc/quantum/quantum.conf
--log-file /var/log/quantum/server.log --config-file
/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --config-file
/etc/quantum/plugins/restproxy/restproxy.ini
