Escalation Services team. Operating System Error (665 – File System Limitation) Not just for DBCC Anymore ★★★★★★★★★★★★★★★ psssqlJune 10, 20155 0 0 0 The operating system error 665, indicating windows error 665 a file system limitation has been reached continues to gain momentum beyond DBCC snapshot the operating system returned error 665 sql server 2012 files. Over the last ~18 months I have reproduced issues with standard database files, BCP output, backups and others. We have windows error code 665 posted previous blogs talking about the NTFS attribute design and associated limitations (665) as the storage space for the attribute structures becomes exhausted. http://blogs.msdn.com/b/psssql/archive/2008/07/10/sql-server-reports-operating-system-error-1450-or-1452-or-665-retries.aspx http://blogs.msdn.com/b/psssql/archive/2009/03/04/sparse-file-errors-1450-or-665-due-to-file-fragmentation-fixes-and-workarounds.aspx Online DBCC has been susceptible to this limitation leveraging a operating system error 665(failed to retrieve text for this error. reason: 15105) secondary stream for copy-on-write activities. The sparse nature of DBCC snapshot or a snapshot database can drive attribute exhaustion. As space is acquired the disk storage location(s) and size(s) are stored in the attribute structures. If the space is adjacent to a cluster already tracked by the file the attributes are compressed into a single entry, spanning the entire size. However, if the space is fragmented it has to be

tracked with multiple attributes. The 665 issue can pop up with larger file sizes. As the file grows it acquires more space. During the space acquisition the attributes are used to track this space. Repro 1 – DBCC Snapshot or Snapshot Database The copy-on-write logic acquires new space as pages are dirtied in the main database. As writes occur to the snapshot target more attributes are used. The space allocations and clusters are by definition and design stored in spare locations. Repro 2 – Database files I can insert data into a database with a smaller auto grow size, each acquiring new disk space. If the disk space is not acquired in strict, cluster adjacent order the growth is tracked with separate attributes. After millions of grows from a large import or index rebuild (usually around 300GB) I can exhaust the attribute list and trigger the 665 error. Repro 3 – BCP BCP extends the output file in the process of simply writing to the file. Each block written has to acquire disk space and it is reliant on adjacent disk space allocation to accommodate a large file. One customer was trying to use a copy of BCP per CPU and the query option to partition the outpu

(retries) ★★★★★★★★★★★★★★★ psssqlJuly 10, 200813 0 0 0 Overview The error: updateuptimeregkey: operating system error 1450 1450/1452 insufficient system resources exist to complete the requested service. These are not a SQL Server create file encountered operating system error 665 based errors. The error cause is related to a depleted system resource (non-paged pool, paged pool ,…). These issues have to be tracked down at the operating system https://blogs.msdn.microsoft.com/psssql/2015/06/10/operating-system-error-665-file-system-limitation-not-just-for-dbcc-anymore/ level. This involves collection of system level performance monitor counters and evaluating the basic health of the overall system. /3GB A commonly overlooked configuration option is the use of /3GB. The /3GB boot switch limits the operating system space to 1GB on a 32 a bit system. If your system is running with /3GB and https://blogs.msdn.microsoft.com/psssql/2008/07/10/sql-server-reports-operating-system-error-1450-or-1452-or-665-retries/ you can't pinpoint the resource depletion consider removing the /3GB boot switch. SQL Server Retries When these errors occur they usually appear during SQL Server I/O operations (ReadFile, WriteFile, ReadFileScatter, WriteFileGather, DeviceIoControl, …) SQL Server identifies the situation, pauses briefly (a few milliseconds) to allow the system to respond and retries the I/O operation.

Once the amount of data stored in the sparse file exceeds the limit further data storage in the file may be prevented. · Windows 2003 - 64GB (Error 1450 returned) · Windows 2008 and Vista - 16GB (Error 665 returned) Windows 2003 Error: The operating system returned error 14

And, when I am able to create them, I get the following errors:Date 2/15/2012 11:37:53 PMLog SQL Server (Current - 2/15/2012 11:39:00 PM)Source spid22sMessageThe operating system returned error 665(The requested operation could not be completed due to a file system limitation) to SQL Server during a write at offset 0x0000123b0f0000 in file 'Z:\DATA\JPE_Snapshot.ss'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

All Forums General SQL Server Forums Data Corruption Issues CHECKDB Failing Reply to Topic Printer Friendly Author Topic tkizer Almighty SQL Goddess USA 38200 Posts Posted-03/04/2014: 18:16:41 DBCC CHECKDB is failing on one of my critical databases, but I don't think there's corruption. Here's the output:CHECKDB found 0 allocation errors and 0 consistency errors in database 'dbname'. Msg 926, Level 21, State 6, Line 1 Database 'dbname' cannot be opened. It has been marked SUSPECT by recovery. See the SQL Server errorlog for more information. Msg 0, Level 20, State 0, Line 0 A severe error occurred on the current command. The results, if any, should be discarded.I manually created a database snapshot and ran checkdb on that, it came back clean:DBCC results for 'dbname_ss'.CHECKDB found 0 allocation errors and 0 consistency errors in database 'dbname_ss'.DBCC execution completed. If DBCC printed error messages, contact your system administrator.I've already opened a case with Microsoft but am wondering if this is unlikely data corruption. When I first spoke with the engineer, I was told to restore the database. But this was before I ran checkdb on the database snapshot. I think I'm encountering a Windows sparse file issue or a filter driver issue. I've got our McAfee team working on some issues with the server that is blocking our exclusions (*.mdf, *.ldf, *.bak, etc).Do you think this is unlikely data corruption given the clean checkdb on the newly created database snapshot?Tara KizerSQL Server MVP since 2007http://weblogs.sqlteam.com/tarad/ tkizer Almighty SQL Goddess USA 38200 Posts Posted-03/04/2014: 18:19:27 Cross posted to Twitter #sqlhelpTara KizerSQL Server MVP since 2007http://weblogs.sqlteam.com/tarad/ tkizer Almighty SQL Goddess USA 38200 Posts Posted-03/04/2014: 18:25:46 Here are the errors in the Error Log:F:\Data1\dbname.mdf:MSSQL_DBCC11: Operating system error 665(The requested operation could not be completed due to a file system limitati
