exact same thing happened to me, I'm having problems turning the db back online and we have NO BACKUP. Tried using DBCC CHECKDB (Reporting,REPAIR_ALLOW_DATA_LOSS) but it failed and encountered this error:

"DBCC CHECKDB

Msg 8930, Level 16, State 11, Line 1

Database error: Database 12 has inconsistent metadata. This error cannot be repaired and prevents further DBCC processing. Please restore from a backup.

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."

This is because of the db being a subscriber any intelligent answer would be appreciated. Thanks.
