Error Starting Pool – Start-CSPool

twitterlinkedinmail

Environment:

Skype for Business (SFB) Server 2015 Standard Edition – 2 Pools

Issue:

After completing Step 3 the certificate request during a SFB deployment the next step was to run the cmdlet Start-CSPool -Idenity PoolFQDN.domain.com upon doing so the following error message was received

Start-CsPool : Please make sure at least 1 machine(s) are in running or starting state to achieve fabric network ring quorum from the following machine list. Also makes sure Windows Fabric Host Service is running on those machines. PoolFQDN.domain.com

At line:1 char:1

+Start-CSPool -PoolFQDN PoolFQDN.domain.com

+CategoryInfo :InvalidOperation (:) [Start-CsPool], Exception FullyQualifiedErrorId: Not enough seed nodes are running. , Microsoft.Rtc.Management.Hadr.StartOcsPoolCmdlet

And also the error in the event log EventID 12304 LS Server, which was definitely a bit weird because it was talking about an Enterprise Edition Server but we are deploying a Standard Edition Server.

The component Live Communications User Services (application:Default) reported a critical error: code 0xC3EE78F8 (Enterprise Edition Server successfully registered with the back-end, but a stored procedure version mismatch was detected.

The service will not start until this problem is resolved

Cause: The database schema and the Enterprise Edition Server were updated by different installation packages.

Resolution:

Ensure both the Enterprise Edition Server and back-end were installed or modified by the same installation page. For more information please refer to http://go.microsoft.com/fwlink/?Linkid=613423.). The service has to stop.


Resolution:

First this error is a bit confusing as normally upon a new deployment without any CU’s the SFB services would start, at that point the CU was applied however not this time.

To resolve the issue here is what was completed:

  1. Re-Ran Step 2 (Install or Update Skype for Business Server System) from the Deployment Wizard. Once completed I re-ran Start-CSPool -PoolFqdn PoolFQDN.domain.com (<- This didn’t work 🙁 )
  2. I downloaded the latest SFB CU and installed it, rebooted the server as per the CU request. Once the server came back up and running all the services started successfully 🙂
    1. I then completed the CU install by updating the Databases.
