This KB article affects W2008 R2 only.
Assume that you try to bring a disk online on a Windows Server 2008 R2-based failover cluster. Additionally, the Update Sequence Number (USN) journal is increased to a large size (such as 4 gigabytes) on the disk volumes. In this situation, it takes a long time to mount the volumes. Additionally, you receive a Stop error message that resembles the following:
Stop 0x0000009E (Parameter1, Parameter2, Parameter3, Parameter4)
Notes
- This Stop error describes a USER_MODE_HEALTH_MONITOR issue.
- The parameters in this Stop error message vary, depending on the configuration of the computer.
- Not all "Stop 0x0000009E" errors are caused by this issue.
This issue occurs because of the large size of the disk volumes. The USN journal file is read in 4-kilobyte chunks when you mount the volumes. When the file is very large, it takes a very long time to mount the volumes.
A supported hotfix is available from Microsoft.
