Public bug reported:
It appears that whenever a lbaasv2 is updated, if the update does not
contain an update to the pool's session_persistence, then the pool's
session_persistence gets cleared. Observe:
Run:
# neutron lbaas-loadbalancer-create --name lb1 private-subnet
# neutron lbaas-listener-create --name listener1 --loadbalancer lb1 --protocol
HTTP --protocol-port 80
# neutron lbaas-pool-create --name pool1 --lb-algorithm ROUND_ROBIN --listener
listener1 --protocol HTTP --session-persistence type=SOURCE_IP
lbaas_sessionpersistences table looks like:
mysql> select * from lbaas_sessionpersistences;
+--------------------------------------+-----------+-------------+
| pool_id | type | cookie_name |
+--------------------------------------+-----------+-------------+
| faa5d800-60c1-49e6-aab7-c3d737098837 | SOURCE_IP | NULL |
+--------------------------------------+-----------+-------------+
1 row in set (0.00 sec)
Now update something other than the session_persistence on the pool:
# neutron lbaas-pool-update --lb_algorithm=ROUND_ROBIN pool1
lbaas_sessionpersistences table looks like:
mysql> select * from lbaas_sessionpersistences;
Empty set (0.00 sec)
