It seems that I have some corruption within a user database. Running DBCC CHECKDB results in the following error:
Msg 8921, Level 16, State 1, Line 1
Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.
I tried running DBCC CHECKALLOC and DBCC CHECKCATALOG. Both complete without an error. Next, I ran DBCC CHECKTABLE on each table. I found a single table that produced the same error as above from DBCC CHECKDB.
When I try to query the table (for instance, SELECT COUNT(*) FROM dbo.Table), SSMS returns this error (which is identical to the corresponding errors in the SQL Server error log and the system event log):
Msg 824, Level 24, State 2, Line 1
SQL Server detected a logical consistency-based I/O error: incorrect pageid (expected 1:98530; actual 57553:769). It occurred during a read of page (1:98530) in database ID 26 at offset 0x000000301c4000 in file 'D:\Program Files\Microsoft SQL Server\MSSQL10.ATLCSETASQL\MSSQL\DATA\xt3_newbraunfels_01.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe 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.
Next, I took the info from above and ran this:
DBCC TRACEON (3604)
DECLARE @DBId INT = DB_ID(DB_Name())
DBCC PAGE( @DBId, 1, 98530 )
I'm trying to interpret the output from DBCC PAGE (see attached). However, I'm not sure how to proceed.
