Hi Shuicheng,

 

All the services on the Active Controller are “enabled-active” and I can see some services “enabled-standby” on the standby controller.

 

Is there any way we can set all the Openstack Services “enabled-active” on both the Active and Standby Node?

Hi Anirudh,

Per my understanding, for duplex, there is always 1 active node and 1 standby node.

The “active/active” or “active/standby” in the document is for “services”, not for node.

If you try to run “sudo sm-dump” in the standby node, you will find some services are “active”, while some services are “standby”.

 

For the 2^nd question, VMs are running in compute node. And for duplex, both controller nodes are compute nodes also.

And the “Active/Standby” is for controller, not for compute function, that is why VMs will run in both node.

 

 

 

Hi Team,

 

Can someone please give me any update on my Query:

 

I need to install StarlingX 2.0 Duplex Bare Metal.

As per the document, there can be 2 modes in which HA controllers can be configure i.e. either “active/active” or “active/standby”
https://docs.starlingx.io/deploy_install_guides/r2_release/bare_metal/aio_duplex.html

 

• Can someone please suggest the steps to configure Active-Active state?
• I have 2 kubernetes pods corresponding to each Openstack Service in Duplex Setup and when I spawn any VM, it goes on any of the two controllers. So, is this the standard implementation in StarlingX? What needs to be done in Active-Standby configuration?
• And, what difference it would have on my deployment in terms of functionality?
