Title:
Trying to remove a load balancer pool (which contains members) via
horizon ends with error
Status in OpenStack Dashboard (Horizon):
New
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
I've tried to remove a pool that has 2 members and a health monitor,
operation failed with the following popup:
"Error: Unable to delete pool. 409-{u'NeutronError': {u'message': u'Pool
f5004d04-4461-4a9a-aa7c-04a9bdfde974 is still in use', u'type': u'PoolInUse',
u'detail': u''}}"
I did expect this operation to fail, I just didn't expect it to be
available in horizon while the pool still has other objects associated
with it and I didn't expect it to leave the pool in "PENDING_DELETE"
status.
The exception from the log file:
