Title:
On mass deletion - some VM's stuck on ERROR due to connection failed
to neutron
Status in OpenStack Neutron (virtual network service):
Expired
Bug description:
Description of problem:
When doing mass deletion (more then 64 VM's parallely), some VM's got stuck on ERROR state with the error:
"Connection to neutron failed: Maximum attempts reached", "code": 500, "created": "2014-06-10T21:34:38Z"
Version-Release number of selected component (if applicable):
openstack-neutron-openvswitch-2014.1-26.el7ost.noarch
python-neutronclient-2.3.4-2.el7ost.noarch
python-neutron-2014.1-26.el7ost.noarch
openstack-neutron-ml2-2014.1-26.el7ost.noarch
openstack-neutron-2014.1-26.el7ost.noarch
How reproducible:
100%
Steps to Reproduce:
1. Setup an environment with a lot of ACTIVE VM's (more then 64)
2. Run mass deletion
for each in `nova list | grep ACTIVE | cut -d"|" -f3` ; do nova delete $each & done
Actual results:
