SQL SERVER – Added New Node in Windows Cluster and AlwaysOn Availability Databases Stopped Working

Almost all the time, whenever there is a wizard, it’s a human habit to go with the defaults and finally click finish. Once of my client sent below email to me. In this blog post we are going to learn about Added New Node in Windows Cluster and AlwaysOn Availability Databases Stopped Working.

Hi Pinal,
We are trying to add new node to the AlwaysOn Availability Group and for that we must add new node to Windows cluster. Before doing this in production, we are trying to our test environment and we ran into issues. We noticed that as soon as node is added in windows, our databases which were part of an availability group went to not synchronizing state. Later I noticed that local disks were added to the cluster under “available storage”.

Have you seen this issue? What is wrong with our setup?


I asked for any error in event log and they shared below.

Log Name: System
Source: Microsoft-Windows-FailoverClustering
Event ID: 1069
Task Category: Resource Control Manager
Level: Error
Description: Cluster resource ‘Cluster Disk 2’ of type ‘Physical Disk’ in clustered role ‘Available Storage’ failed. The error code was ‘0x1’ (‘Incorrect function.’)

I told them that they must have followed the wizard and must have forgotten to “uncheck” the highlighted checkbox.

This is the default setting and has caused issues for many, including me during the demo. They also confirmed the same. What is the solution now?


To work around this problem, we must remove the disk resource from Failover Cluster Manager. Once done, we need to bring these drives online in Disk Management once they are removed from Failover Cluster Manager.

Have you run into the same issue? Anywhere default setting in the wizard has caused the problem?
