Known Causes
4 known causesACFS File System Corruption
Underlying file system corruption can lead to the loss or damage of critical metadata, including the data extent list for a file.
Underlying Storage Device Failure

Abrupt System or ACFS Shutdown
An unplanned power loss or an improper shutdown of the ACFS file system can leave metadata in an inconsistent state, causing extent lists to become unlocatable.
ACFS Software Bug
Rarely, a software bug in ACFS or an issue during an upgrade process can introduce metadata inconsistencies that lead to this error.
