Symptoms
This issue occurs when the following conditions are true:
-
You have a Network File System (NFS) file server which is hosted on a two-node Windows Server 2012-based clustered storage server.
-
You have the Data Deduplication feature enabled.
-
The NFS service takes a long time for failover, and then the Resource Hosting Subsystem (RHS) times out.
Also, assume that you have NFS clients that are running Windows or UNIX access the NFS file server. In this situation, when you have many clients (local or remote applications, such as Server Message Block (SMB) or FTP) access this share, sharing violations occur on the server-side intermittently. It causes a brief outage of certain operations, such as directory listing, which can cause third-party applications to fail.
Cause
This issue occurs because many reparse points are generated by the Data Deduplication service.
