Fatal error 823

What is SQL error 823?

A SQL Server database encounters error 823 when an I/O operation (read or write request) fails. This usually happens due to issues with the operating system, drivers, or hardware issues. The SQL error 823 may also occur due to inconsistencies in the file system or a corrupted database file.

The complete text of the SQL 823 error message looks similar to:

In the error message, 823 is the error code. The severity level 24 means that the error occurred due to problems with the hardware or software. The state 2 is used to differentiate the error from other errors with the same number but in a different state.

Further, the error provides the following information:

• The data file (usually a .MDF file) against which the I/O (read or write) operation was performed.
• The offset, i.e., the physical byte offset from the start of the file, dividing it by 8192 will help you find the logical page number that is corrupted due to the error.
• Identifies whether a read or write request was made to a device.

What problems are associated with the 823 IO error?

This problem can be related to the following problems:

1. A Torn Page
2. Bad Page ID
3. Insufficient bytes transferred

What is a torn page?

It is a page that was incorrectly written. We could say Torn Page Detection writes a bit for every 512 bytes on the page. It helps detect a page that is not successfully written to disk. But, it does not tell if the data stored to disk is actually correct as a couple of bytes may have been written incorrectly.

What is the error message for the torn page error?

The error will be like this one:

How can I detect torn page IO error?

You can detect these errors when you run the CHECKDB command in your database.

What is Bad Page ID?

It is when the header page ID is not the same as the expended one when reading in the disk.

Why is the error insufficient bytes transferred produced in SQL Server?

It means that the API call was invoked successfully, but the bytes transferred are not the expected ones.

How to solve SQL Server error 823 ?

The first step would be to run a DBCC CHECKDB command and check if it returns consistency errors. If it does, try to restore your database from a backup. Once the database is restored, run a CHECKDB to verify that the problem is solved.

If the problem persists or backup is not available, try to repair the database using the following T-SQL statement:

DBCC CHECKDB (DB_NAME, REPAIR_REBUILD);

To repair the database, you must restrict its usage to a single user. This requires changing the database state to Single-user mode. To do so, run the following T-SQL query:

ALTER DATABASE DB2 SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

You can also set the database to a Single-user using the point-in-click interface in SQL Server Management Studio (SSMS). For this, right-click on the database in SSMS and go to the Options page. On the ‘Options’ page, choose the SINGLE USER option from the Restrict Access drop-down box, then click OK.

After setting the database to Single_user mode, repair the database, and run ‘DBCC CHECKDB’ again to verify that the database was repaired.

Note: If the error persists, an issue with the hardware might have caused SQL error 823. In that case, you will need to repair your hard disk. Contact the IT members in charge of the hardware. Check also if there are fragmentation problems in the hard disk.

If you have a Torn page error, you can use the CHECKSUM and the torn page detection to repair and verify the errors.

What Else You Can Do to Resolve SQL Error 823?

Use Stellar Repair for MS SQL to fix database consistency errors reported by DBCC CHECKDB and preview the recoverable data. This SQL repair tool  can be downloaded from the link below.

This software will repair the .MDF/.NDF files of SQL Server database. Before using the software, make sure to stop the SQL Server Service first. It is recommended to stop the service using the SQL Server Management Studio (SSMS) or the SQL Server Configuration Manager.

Now follow these steps to repair and recover your SQL database file:

• Browse or search the corrupt .MDF file.
• Once the .MDF file is uploaded, press the Repair button.

Note: If you have one or multiple secondary data files (.NDF file) associated with your database, then put all the NDF files at the location of the MDF file. Once everything is done, you can restart the SQL Server Service and rerun the CHECKDB command.

• Run standard scan to repair the selected database file quickly.

• Preview the repairable database objects and select all or specific objects you want to restore. Next, press the Save button from the File menu.

• Enter the details as shown in the following screen to complete the file saving process.

Once the software repairs the .MDF file, you will no longer see the SQL Server error 823.

MSSQLSERVER error 823

Applies to: SQL Server (all supported versions)

Details

Explanation

SQL Server uses Windows APIs (for example, ReadFile, WriteFile, ReadFileScatter, WriteFileGather) to perform file I/O operations. After performing these I/O operations, SQL Server checks for any error conditions associated with these API calls. If the API calls fail with an Operating System error, then SQL Server reports Error 823.

The 823 error message contains the following information:

• The database file against which the I/O operation was performed
• The offset within the file where the I/O operation was attempted. This is the physical byte offset from the start of the file. Dividing this number by 8192 will give you the logical page number that is affected by the error.
• Whether the I/O operation is a read or write request
• The Operating System error code and error description in parentheses

Operating system error: A read or write Windows API call is not successful, and SQL Server encounters an operating system error that is related to the Windows API call. The following message is an example of an 823 error:

You may or may not see errors from the DBCC CHECKDB statement on the database that is associated with the file in the error message. You can run the DBCC CHECKDB statement when you see an 823 error. If the DBCC CHECKDB statement does not report any errors, you probably have an intermittent system problem or a disk problem.

Additional diagnostic information for 823 errors may be written to the SQL Server error log file when you use trace flag 818. For more information, see KB 826433: Additional SQL Server diagnostics added to detect unreported I/O problems

Cause

The 823 error message usually indicates that there is a problem with underlying storage system or the hardware or a driver that is in the path of the I/O request. You can encounter this error when there are inconsistencies in the file system or if the database file is damaged. In the case of a file read, SQL Server will have already retried the read request four times before it returns 823. If the retry operation succeeds, the query will not fail but message 825 will be written into the ERRORLOG and Event Log.

Ошибка MSSQLSERVER 823

Применимо к: SQL Server (все поддерживаемые версии)

Сведения

Объяснение

SQL Server использует API Windows (например, ReadFile, WriteFile, ReadFileScatter, WriteFileGather) для выполнения операций ввода-вывода файлов. После выполнения этих операций ввода-вывода SQL Server проверяет наличие ошибок, связанных с вызовами этих API. Если при вызове API происходит сбой из-за ошибки операционной системы, SQL Server сообщает об ошибке 823.

В нем содержится следующая информация.

• Файл базы данных, для которого была выполнена операция ввода-вывода.
• Смещение в файле, где была предпринята попытка выполнить операцию ввода-вывода. Это смещение физического байта от начала файла. Деление этого числа на 8192 приводит к возвращению номера логической страницы, на которую повлияет ошибка.
• Является ли операция ввода-вывода запросом на чтение или запись.
• Код ошибки операционной системы и описание ошибки в круглых скобках.

Ошибка операционной системы: вызов API Windows для чтения или записи не выполнен, и SQL Server обнаруживает ошибку операционной системы, связанную с вызовом API Windows. В следующем примере показано сообщение об ошибке 823:

Ошибки инструкции DBCC CHECKDB в базе данных, связанной с файлом, могут быть не указаны в сообщении об ошибке. Вы можете выполнить инструкцию DBCC CHECKDB, если появилась ошибка 823. Если инструкция DBCC CHECKDB не сообщает о каких-либо ошибках, возможно, возникла временная неполадка системы или проблема с диском.

Дополнительные диагностические сведения для ошибок 823 могут быть записаны в файл журнала ошибок SQL Server при использовании флага трассировки 818. Дополнительные сведения см. в статье KB 826433: добавлены дополнительные средства диагностики SQL Server для выявления незамеченных проблем ввода-вывода.

Причина

Сообщение об ошибке 823 обычно указывает на наличие проблемы с базовой системой хранения данных, оборудованием или драйвером в пути запроса ввода-вывода. Эта ошибка может возникать, если в файловой системе возникли несоответствия или если файл базы данных поврежден. В случае чтения файла SQL Server будет четыре раза повторять запрос на чтение, прежде чем вернет ошибку 823. Если повторная операция завершается успешно, запрос не завершится ошибкой, но в журнал ошибок и журнал событий будет записано сообщение 825.
