We are using havana, on rhel, with neutron/openvswitch.
I have defined an external network, with an IP pool. This pool is also used for floating IPs. I have currently defined an allocation pool with 100 adresses.
Question: How do I modify that. How do I enlarge this range?
I have found out that you can't do this using the command line. However you can do this by manipulating the database.
What I did was log on using a mysql client to the ova_neutron database and then:
For example, suppose that the old range was 8.8.8.100 -> 8.8.8.200 and I wanted it to be 8.8.8.100 -> 8.8.9.255
First find out what the id for the allocation pool is:
select * from ipallocationpool;
suppose you find out that your pool has id e813be7a-b87d-4b74-b702-9b349199c2c7
update ipallocationpools set last_ip='8.8.9.255' where id = 'e813be7a-b87d-4b74-b702-9b349199c2c7';
insertinsert into ipavailabilityranges (allocation_pool_id,first_ip,last_ip)
values ('e813be7a-b87d-4b74-b702-9b349199c2c7','8.8.8.101','8.8.9.255');
On our stack this did the trick...
yes u can do that if you are using dashboard go to your external network and to that and if there is no option, then go to neutron service by login using keystone file and increase your external network from there using neutron command or you may also do this by changing neutron database.
