Problems with Floating IPs
|
|
I just got my cluster up. I have multiple compute nodes in HA with
VLAN networking. I have a "controller" backend machine. All servers
are connected to the same switch. I had a similar setup using crowbar
so I know VLAN'ing is working on the switch.
When I try to run "nova floating-ip-pool-list" from any node (the
controller node without nova-network or a compute node with
nova-network) I get: ERROR: The server has either erred or is
incapable of performing the requested operation. (HTTP 500)
However, when I run "nova-manage floating list" I see all the IP's in
the floating pool. Here is the stacktrace I have seen in the
nova-api.log (I also see the dashboard error out as expected)
