MSSQL on Windows: Table error: Allocation page has invalid page header values.

Microsoft.SQLServer.Windows.EventRule.DBEngine.Table_error__Allocation_page_has_invalid__page_header_values.__1_5_Rule (Rule)

The page specified has an invalid page header.

Knowledge Base article:

Causes

The page specified has an invalid page header.

Per-state information:

State 1 : PAGE_TYPE may be 'GAM_PAGE', 'SGAM_PAGE', 'ML_MAP_PAGE', 'DIFF_MAP_PAGE', or 'IAM_PAGE'.

State 2 : PAGE_TYPE is 'PFS_PAGE'.

State 12 : PAGE_TYPE is 'PFS_PAGE'. This state is fatal to the command.

Resolutions

HARDWARE FAILURE

Run hardware diagnostics and correct any problems. In addition, examine the Microsoft Windows NT system and application logs and the SQL Server error log to see if the error occurred as the result of hardware failure. Fix any hardware-related problems.

If you have persistent data corruption problems, try to swap out different hardware components to isolate the problem. Check to ensure that your system does not have write caching enabled on the disk controller. If you suspect this to be the case, contact your hardware vendor.

Finally, you might find it beneficial to switch to a completely new hardware system, including reformatting the disk drives and reinstalling the operating system.

RESTORE FROM BACKUP

If the problem is not hardware related and a known clean backup is available, restore the database from the backup.

DBCC CHECKDB

If no clean backup is available, execute DBCC CHECKDB without a repair clause to determine the extent of the corruption. DBCC CHECKDB will recommend a repair clause to use. Then, execute DBCC CHECKDB with the appropriate repair clause to repair the corruption.

CAUTION: If you are unsure what effect DBCC CHECKDB with a repair clause has on your data, contact your primary support provider before executing this statement.

Repair depends on the page type (see error 8938 for page types):

PFS_PAGE:

Nothing will be done because PFS pages cannot be repaired.

IAM_PAGE:

The IAM chain will be patched so that further repairs can be run. This may involve removing the corrupt page.

All other allocation pages will be reformatted and rebuilt (if the undocumented repair option was specified).

If running DBCC CHECKDB with one of the repair clauses does not correct the problem, contact your primary support provider.
