FIX: DBCC Shrinkdb Fails with Error 7991 (158892)

SYMPTOMS

If the default database size in the SQL Server Configuration Values is set to a value that is greater than the actual size of a database, you receive the following error when trying to shrink the database:

Error 7991:
Unable to shrink database '%.*s' as it contains %d pages. Minimum pages %d.

The database consistency checker (DBCC) command shrinkdb(<dbname>) works correctly and shows the size to which the database can be shrunk, but you will also receive error 7991, if the condition above is true. It makes no difference whether you use the user interface or the DBCC shrinkdb Transact- SQL command.

WORKAROUND

To work around this problem, set the Database Size configuration value to a value that is less than the size of the database you want to shrink.
