Symptoms
Assume that you have a database that contains tables with clustered columnstore index in SQL Server 2017. When you run the statement DBCC CHECKDB WITH ALL_ERRORMSGS, NO_INFOMSGS, PHYSICAL_ONLY in the database, a dump file is generated and you may receive error messages that resemble the following:
Table error: Object ID ObjectID, index ID IndexID, partition ID PartitionID, alloc unit ID ID (type In-row data). The off-row data node at page (1:1749624), slot 1, text ID TextID is referenced by page (0:0), slot 0, but was not seen in the scan.
CHECKDB found 0 allocation errors and 1 consistency errors in table 'TableName' (object ID ObjectID).
CHECKDB found 0 allocation errors and 1 consistency errors in database 'DatabaseName'.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (DatabaseName).
