This article describes an update that makes the cluster disks log the identity information about the faulty disks to the system event log on a Windows Server 2012 R2-based failover cluster. Therefore, you can easily identify which disk in the storage pool should be removed or replaced.
Consider the following scenario:
- You create a Windows Server 2012 R2-based failover cluster that contains at least two cluster nodes.
- You create a Storage Spaces pool that contains at least two failover clustering-capable disks.
- You add the Storage Spaces pool to the failover cluster and bring the Storage Spaces resource online.
- The Storage Spaces resource tries to come online on a different cluster node after an unplanned failover event occurs.
