ERRORLOG顯示數(shù)據(jù)庫(kù)頁(yè)面2538730損壞:
SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x464ff469; actual: 0x48a7f5a1). It occurred during a read of page (1:2538730) in database ID 5 at offset 0x000004d79d4000 in file '/var/opt/mssql/data/realxxxxx.mdf'. Additional messages in the SQL Server error log or operating system error 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.
