Deskpro HA has the ability to force a node promotion in the case of a main node that is having issues. Any standby node that is sync'd can be promoted to main and this will force the current main node out of the cluster.

On the standby node that you want to promote, run a cluster check to get the node Id:

opc cluster node list
 copy

In this case we can see that the main node is 192.168.100.54, and we are on the server node 192.168.100.63. The * next to the hostname indicates which node you are currently logged onto. Make a note if the node Id that we are going to promote then run the following:

opc cluster node promote -i  --force
 copy

So for our example it would be:

opc cluster node promote -i 20f0588e-df3a-4d9d-a66f-edc2e07a4a23 --force
 copy

This will force the standby node to the main role and remove the previous main node from the cluster. You can check this with the cluster node list command:

opc cluster node list
 copy
