This contains Windows Storage Server 2008 Update 1 and Update 2 which consist of updates for the following issues: • KB968675 - Storport Update This update prevents a memory leak that is caused by a temporary unit condition. • KB970662 - Single Instance Storage (SIS) Update This update resolves the following issues with SIS: A memory leak can occur with Groveler.exe if a forced rescan is initiated. There can be timing issues in SIS copy-on-first-write operations. NTFS re-ordering might be incorrectly handled after a forced shutdown. • KB971191 - SIS links that have file sizes less than 1KB get set to normal files after restoring SIS v1 data to a SIS v2 volume. This issue can occur when backing up and restoring SIS files (links) that have been truncated to a length less than or equal to 1 KB from a migrated Windows Storage Server 2003 R2 SIS-enabled volume to Windows Storage Server 2008. • KB970658 – iSCSI initiator appears to fail on reconnection After a lost iSCSI initiator connection is recovered, the session state in iSCSI Initiator interface may continue to display "Reconnecting." This issue only applies to application servers connecting to Microsoft iSCSI Software Target using the iSCSI Initiator. • KB971365 – Added support for GPT disks greater than 2TB. This update supports assigning a GPT disk (greater than or equal to 2TB) to a failover cluster using the Share and Storage Management MMC snap-in. • KB974564 - Single Instance Storage (SIS) Update This update resolves the following issues with the SIS filter driver: The SIS filter incorrectly uses paged memory for copy-on-first-write requests and SI_COPY_THREAD_REQUEST. SIS may corrupt link files that have data written beyond end-of-file (EOF). This update prevents the issue. NOTE: SIS is only available on the Standard and Enterprise editions of the operating system. Only the necessary updates will be applied to the system.
