This has been fixed by first checking whether the tables exist. As

a result, the upgrade from version 3 to version 4 succeeds even if

LoadBalancerPlugin is in use.

There are three known issues when upgrading version 3 to version 4

with LoadBalancer. They will be fixed in a future release.

1) Issue one is with respect to re-creating table 'vips'. This

will be fixed in a future release. To work around this issue run

the command:

neutron-db-manage --config-file /etc/neutron/neutron.conf --

config-file /etc/neutron/plugin.ini stamp f489cf14a79c

prior to the database upgrade.

2) The workaround for the second issue is renaming device_driver

path in /etc/neutron/lbaas-agent.ini from

quantum.plugins.services.agent_loadbalancer.drivers.haproxy.namesp

ace_driver.HaproxyNSDriver

neutron.services.loadbalancer.drivers.haproxy.namespace_driver.Ha

proxyNSDriver

3) To solve the third issue, the following command must be run in

the mysql command-line in neutron database:

INSERT INTO providerresourceassociations (resource_id,

provider_name) SELECT id, 'haproxy' FROM pools;

This enhancement enables mysqld performance improvement if users

add the following configuration options to the /etc/my.cnf file:

innodb_buffer_pool_size = (10-20% of availble memory)

innodb_flush_method = O_DIRECT

innodb_file_per_table

These changes are expected to be implemented in the next release.

BZ #11024 6 6

It is recommended that you do not run sample scripts when

installing production systems. Sample scripts are for

demonstration and testing only. Specifically, the openstack-demo-

install script will create OpenStack Keystone accounts with

default credentials.
