Title:
L3_agent: if openvswitch fails to restart, _rpc_loop will block
forever.
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
Related to bug 890180
How to reproduce the bug in a devstack environment.
1. To simulate that the ovs daemon crashs, and we are not able to
successfully restart it.
$ sudo /etc/init.d/openvswitch-switch stop
2. Remove an interface from a router. Because of the ovs daemon is down,
ovs-vsctl will
waits forever. As a result, _rpc_loop hangs waiting for _process_routers
with holding
the lock.
$ neutron router-interface-remove router2
0a33e6c2-9176-4d88-840e-3879cbee5fd2
3. Try to assign a floating IP to an instance
$ neutron floatingip-associate c6b3ee4a-1eac-4438-a561-9aaf57e1b373
17e11c92-8707-4941-bc2d-455a1b15707d
Expected results:
The floating IP has been added to the qg-* device.
It's OK for the moment if we can't remove the interface from the router.
Actual results:
The floating IP has not been added to the qg-* device.
_rpc_loop hangs without any explicit log messages about the blocking.
