SnapCenter SQL 日志备份失败、并显示错误：操作系统返回错误21

Windows事件查看器显示：Volume L:\<DB> (\Device\HarddiskVolume119) requires an Online Scan. An Online Scan will automatically run as part of the next scheduled maintenance task. Alternatively you may run "CHKDSK /SCAN" locally via the command line, or run "REPAIR-VOLUME <drive:> -SCAN" locally or remotely via PowerShell.

Additional messages in the SQL Server error log and system event log may provide more detail.
