Oracle Database Error ACFS-07050: ACFS Extent List Inconsistency
Description
This error indicates a critical inconsistency within the Oracle Automatic Storage Management Cluster File System (ACFS) metadata. It means that the extent list, which tracks the physical allocation of a file's data blocks, has fewer entries than the file system expects for a specific file, suggesting corruption or a severe structural problem within the ACFS volume.
Error Message

Known Causes
3 known causesUnderlying Storage Hardware Failure
Malfunctions in the disk drives, storage controllers, or interconnects can corrupt ACFS metadata, leading to inconsistencies in file extent lists.
Abrupt System Shutdown or Power Loss
An ungraceful shutdown or power interruption can prevent ACFS from properly flushing metadata changes, leaving the extent lists in an inconsistent state.
ACFS Software Bug or Logical Corruption
Rarely, a software defect within the ACFS driver or a logical corruption during file system operations can lead to incorrect extent list tracking.
