Symptoms

Consider the following scenario:
  • You have a failover cluster on some computers that are running Windows Server 2008 R2.
  • The cluster has many disks.
  • You click Add a disk in the Failover Cluster Manager console to add an extra storage disk on one cluster node.
In this scenario, you receive a Stop error message that resembles the following after a while:
0x0000009E ( parameter1 , parameter2 , parameter3 , parameter4 )
USER_MODE_HEALTH_MONITOR
Notes
  • The parameters in this Stop error message may vary, depending on the configuration of the computer.
  • Not all "0x0000009E" Stop errors are caused by this issue.
Additionally, you may experience the following issues if a cluster has many disks. For example, the cluster has more than 200 hard disks.
  • The Cluster service takes a long time to start.
  • The failover or shutdown operation of cluster resources takes a long time to complete.
  • The operation that adds a new storage disk into the cluster takes a long time to complete.

Cause

When you add extra disks on a cluster that has lots of disks, the thread pool in the Cluster service may be exhausted.

Resolution

To resolve this issue, install the following hotfix on a computer that is running Windows Server 2008 R2. The following hotfix optimizes the hard disk resource implementation and improves the hard disk performance in a Windows Server 2008 R2 cluster.
