Public bug reported:

In my newest devstack encironment with lbaas v2, when I create a lbaas
pool with a PENDING_UPDATE state loadbalancer , the server return error
with "Invalid state PENDING_UPDATE of loadbalancer resource 422c211a-
ca32-4def-9681-a80f37375191", but when I do "neutron lbaas-pool-list",
the failed pool is shown on the screen.
