MSSQLSERVER_823 Other Versions SQL Server 2014 SQL Server 2012 Topic Status: Some information in this topic is preview and subject to change in future releases. Preview information describes new features or changes to existing features in Microsoft SQL Server 2016 Community Technology Preview 2 (CTP2). Details Product Name SQL Server Event ID 823 Event Source MSSQLSERVER https://msdn.microsoft.com/en-us/library/aa337267.aspx Component SQLEngine Symbolic Name B_HARDERR Message Text The operating system returned error %ls to SQL Server during a %S_MSG at offset %#016I64x in file '%ls'. 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. Explanation A Windows read or write request has failed. The error code that is returned by Windows and the corresponding text are inserted into the message. In the read case, SQL Server will have already retried the read request four times. This error is often the result of a hardware error, but may be caused by the device driver. For more information about error 823, see http://support.microsoft.com/kb/828339. For more information about I/O errors, see Microsoft SQL Server I/O Basics, Chapter 2. User Action Check for additional information in the system event log. Contact the hardware manufacturer or Microsoft Customer Services and Support to determine the cause and corrective action. After the hardware error is fixed, restore all databases and run DBCC CHECKDB. Community Additions Show: Inherited Protected Print E

Hence by the time CheckDB ran, the page had long since been deallocated. Deallocated pages can't be checked with checkDB as they are not part of the consistent database structure.That s

What does this error mean, and what can i do about it? I tried DBCC CHECKDB('mydatabase') but i only got more error messages.

An 823 message is what I call a 'hard I/O error'. SQL Server asks the OS to read a page and it says no - this means the I/O subsystem couldn't read the page in question. The CHECKDB output means that it couldn't create the internal database snapshot that it uses to get a transactionally-consistent point-in-time view of the database. There are a number of different causes of this: There may not be any free space on the volume(s) storing the data files for the database The SQL service account might not have create-file permissions in the directory containing the data files for the database If neither of these are the case, you can create your own database snapshot and run DBCC CHECKDB on that. One you have, run the following: DBCC CHECKDB (yourdbname) WITH NO_INFOMSGS, ALL_ERRORMSGS If you post the results, I'll interpret them for you (I wrote DBCC CHECKDB for SQL 2005) Whatever the results are, you're looking at either restoring from a backup, extracting data to a new database, or running repair. Each involves varying amounts of downtime a
