Hi, We've an Umbraco 10.8.2 site in a load balanced environment. Following the documentation we need to set the right *serverrole * to the backoffice and frontend server by implementing a **custom ServerRegistrarComposer**: https://docs.umbraco.com/umbraco-cms/v/10.latest-lts/fundamentals/setup/server-setup/load-balancing/flexible-advanced *Question: * When we do this the database table umbracoServer won't be filled, is that correct? Or should this table always be filled?

Yep nothing gets logged to the table as you've explicitly set away from the electedServerRole... https://github.com/umbraco/Umbraco-CMS/blob/contrib/src/Umbraco.Infrastructure/HostedServices/ServerRegistration/TouchServerTask.cs#L67-L73

Hi @Mike Chambers But what is the best practise in this case? Should we set the electedServerRole? And if so, how should we do that exaclty? We still get problems after a deploy to these 2 servers. The index of one of these servers is empty or not fully reindexed. It changes from server to server, so one time it's the backend server and the other time it is the frontend server. Thanks in advance!

Nope, you should explicitly set the roles when loadbalancing, and the table will cease to receive data. (To stop it doing what I think you are seeing where servers are getting elected based on which one is live fiest) You can check for the correct role in views with

csharp
@inject IServerRoleAccessor serverRoleAccessor;    @(serverRoleAccessor.CurrentServerRole)

Did you also notice that the examine settings should be different between

schedulingpublisher

and

subscriber

? https://docs.umbraco.com/umbraco-cms/v/10.latest-lts/fundamentals/setup/server-setup/load-balancing/azure-web-apps#lucene-examine-configuration I think you would take the same approach for any flexible setup as azure.

Hi @Mike Chambers We have added logs to check the role of the server and that seems correct for both servers.

Sorry 1.. if you don't want overlappng.. 😉 https://learn.microsoft.com/en-us/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet#scaling When are logging for

IsSchedulingPublisherServer: False

are you actually checking that your subscribers are Role == Subscriber and not just

!schedulingPublisher

? (sorry if that's asking you to suck eggs) We have

csharp
using Umbraco.Cms.Core.Sync;

namespace www.Extensions.LoadBalancing
{
    public class SetServerRegistrarRoles : IServerRoleAccessor
    {
        private readonly IWebHostEnvironment _env;

        public SetServerRegistrarRoles(IWebHostEnvironment env)
        {
            _env = env;
        }

        public ServerRole CurrentServerRole
        {
            get
            {
                return _env.EnvironmentName switch
                {
                    "Development" => ServerRole.Single,
                    "Production" or "Staging" or "Local.Publisher" => ServerRole.SchedulingPublisher,
                    _ => ServerRole.Subscriber,
                };
            }
        }
    }
}

Note the default of

ServerRole.Subscriber

as from memory there was something where the Environment name was returning null or empty in some scenario....
