Hi Alioune,
Please find me in IRC * #openstack-neutron *name:* mohankumar*
Yes ,the error looks confusing , but logs at "2016-08-16 17:32:35.255 "
showing networking_sfc.services.sfc.drivers.ovs.driver function
called as *'ingress':
None * , Hence the create port_chain at sfc driver manager failed . Please
check q-svc log in neutron-log.zip
port_chain db record created then sfc driver got failed hence the code
attempting to remove db entry but it can't remove due to key constraints .
https://github.com/openstack/networking-sfc/blob/33d8014c1ef2d7a83578145f44bc41b1453cb257/networking_sfc/services/sfc/plugin.py#L41-L57
So you getting both errors (from q-svc log)
[01;31m2016-08-16 17:32:35.654 TRACE networking_sfc.services.sfc.plugin
[01;35m [00mSfcDriverError: create_port_chain failed.
01;31m2016-08-16 17:32:35.976 TRACE networking_sfc.services.sfc.plugin
[01;35m [00mSfcDriverError: delete_port_chain failed.
we not seen such issue in master / liberty stable branch , please let me
know your sfc code base or you did any local code changes ?
Thanks.,
Mohankumar.N
