A physical disk resource may unexpectedly fail or go offline when the IsAlive function is executed on a Windows Server 2008 cluster node

View products that this article applies to.


Consider the following scenario:
  • You have a Windows Server 2008 cluster node.
  • The IsAlive function is executed on the cluster node while a file is being accessed in the root folder of the cluster disk.
In this scenario, a physical disk resource on the Windows Server 2008 cluster node may unexpectedly fail or go offline. This behavior occurs randomly.

When the IsAlive function is run while a file in the root folder of a Windows Server 2008 cluster node is being accessed, the logic of the IsAlive function is incorrect. For example, Microsoft SQL Server and Microsoft Exchange Server may store temporary files in the root folder, and these files are frequently created and deleted. If these temporary files are accessed while the IsAlive function is being called, the disk resource and any dependent resources may encounter a failed state. This triggers the cluster service restart logic.
