I have some DB corruption and I don't have a good recent backup. All data appears to be fine, but when I run a DBCC CHECKDB I get this
Msg 8905, Level 16, State 1, Line 1
Extent (1:1534320) in database ID 7 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
When I google the error I find a Microsoft Article about the error which leads me to this table. https://technet.microsoft.com/en-us/library/Aa275767(v=SQL.80).aspx
Can someone help me better understand this error and what impact it could have? It appears everything is working properly. I have tried copying the DB to a test server and running DBCC CheckDB ('Database', REPAIR_ALLOW_DATA_LOSS)and even that will not remove the Allocation Error.
