Symptoms

This is a Single Instance Storage (SIS) update rollup for Windows Storage Server 2008 R2 and Windows Server 2008 R2. This update rollup resolves the following issues:

Issue 1

After a file is truncated to empty size on a SIS volume by using CreateFile with the TRUNCATE_EXISTING creation disposition:
  • If the file is read without reopening it, the system may return data as if the file was not truncated. For example, if the original file is 2 megabytes (MB) and is opened by using CreateFile with the TRUNCATE_EXISTING creation disposition. When the first 1 MB is read, the system may return the original 1 MB of content even though the file size is zero.
  • If the file is written without reopening it, the system may behave as if the file was not truncated. For example, if the original file is 2 MB and is opened by using CreateFile with the TRUNCATE_EXISTING creation disposition. When the first 1 MB is written with new data, the new file may be 2 MB with the first 1 MB of new data and second 1 MB of original data.
Issue 2

When a file is compressed or decompressed on a SIS volume and the file was previously changed and the modification was interrupted or failed, the file may be corrupted.

Issue 3

When a file is accessed on a SIS volume and the volume is under a high stress situation, the server may stop responding to all requests to the SIS volume.


Important

Windows Storage Server products are OEM-only products. OEMs must set up a contract with Microsoft Licensing through their OEM account managers before the OEMs can access update packages for Windows Storage Server. This update rollup is distributed only through Microsoft OEM Online. Send questions about this update package to the following email address:
naspm@microsoft.com

Cause

Issue 1

This issue occurs because the SIS filter does not filter the FileAllocationInformation information class of IRP_MJ_SET_INFORMATION requests.

Issue 2

This issue occurs because certain read operations that originate from NTFS for compression or decompression on SIS-managed files are invisible to the SIS filter. This prevents the SIS filter from returning the actual file data and causes the file corruption.

Issue 3

This issue occurs because the SIS filter incorrectly causes a deadlock situation on the SIS volume.
