Hi guys,<br>
<br>
i'm looking since days for a solution to solve the SPOF (single point of<br>
failure) of the lbaas. A easy solution with a config option is not<br>
available yet.<br>
<br>
The next option is to install/configure some not OpenStack related tools<br>
like pacemaker. I realise my L3-Agent faiover with an self writen RA for<br>
pacemaker to switch routers on broken l3 agent to the running on with<br>
the neutron API.<br>
The same can be workin with LbaaS but there's a problem again:<br>
<br>
- No API function to switch a pool from agent A to agent b<br>
- configurations of HAProxy replicate => this can be solvd with drbd or<br>
some shared network storage like NFS<br>
- Devices are not the same => L3 switch router from agent A (broken) to<br>
agent B the devices names are not the same<br>
-<br>
<br>
Is there any solution to solve this SPOF ? I mean a LB should not only<br>
scale/balancing your cluster/application the second task is the failover<br>
of broken members.<br>
<br>
<br>
<br>
<br>
Thx and cheers<br>
Heiko<br>
