The sizes of the following server message block (SMB) event logs are too small in Windows 8.1 and Windows Server 2012 R2:
In SMB Client, the size of the Operational log is only 1 megabyte (MB). This limits the log to approximately 1,700 events. This is probably not enough for a compute cluster.
In SMB Server, the sizes of the Operational, Connectivity, and Security logs are each only 1 MB. This limits the logs to approximately 1,700 events. This is probably not enough to diagnose critical issues on a storage cluster.
To resolve this issue, install update 2919355. After you apply this update, the size of each of the logs is increased to 8 MB.
