Consider the following scenario:
• You have a failover cluster that is running Windows Server 2008
In this scenario, the disk fails to come online and shows a status of Online Pending.
The issue occurs because the cluster resource dll (clusres.dll) tries to open every file under the root folder of the cluster disk during the cluster disk online process. If there are too many files, the online process will time out and the disk resource will fail to come online.
To work around the issue:
1. Do not store large amounts of files in the root folder.
Cluster <ClusterName> /Res <Resource Name> /Priv DiskRunCHKDSK=4
