Remove SBC Cluster and just use 1 SBC

[OmarT]

Hello,

We are running into problems where one of the HA SBCs went down and was removed. Now the client is getting disconnected every now and then and we are looking to remove the HA Cluster all together until we are ready to put in another secondary device if they do decide to do this. What would be the process in this? I did read https://www.3cx.com/docs/sbc-high-availability-cluster/#h.l13gvsgyesmf (shown below) but once I remove the cluster, do I just run the SBC install script wget https://downloads-global.3cx.com/downloads/misc/d10pi.zip; sudo bash d10pi.zip or should I reimage the device and just make sure to enter the same link/credentials from the 3cx portal so that current phones do not need to be reprovisioned?

Removing an SBC Cluster Node​

To remove a member node from the SBC cluster, use these steps:

1. Run the SBC HA cluster installation script:

wget http://downloads-global.3cx.com/downloads/sbccluster/3cxsbc.zip -O- | sudo bash

1. When prompted, select the option to uninstall the cluster.
2. Select “Skip” when prompted to remove the cluster resources, unless you are also removing the cluster completely.
3. Select the option to purge the SBC service.

It depends on your level of linux-fu. If you know what you are doing, the above steps plus perhaps some manual purging of the clustering bits (if the above script doesn't do it) should suffice. You would then want to change the IP of the single Pi to the previous cluster IP and then reinstall. If the above doesn't make sense, re-image and then re-install, again using the cluster IP which is the one the phones were talking to.

Great! I understand and will go ahead and do this. I greatly appreciate it @cobaltit.
