Oracle Database Error ACFS-07064: ACFS File Metadata Inconsistency
Description
This error indicates a critical inconsistency in the Oracle ACFS (Automatic Storage Management Cluster File System) metadata. Specifically, the internally recorded allocation size for a file does not match the actual sum of its data extents on disk. It points to potential file system corruption or a serious issue during file operations.
Error Message
file _AllocationSize value not equal to sum of extents found: string , but expected to find: string for file: string
Known Causes
4 known causesACFS Metadata Corruption
The internal structures that manage file allocation within ACFS have become corrupted, leading to a discrepancy between the recorded and actual file sizes.
Unexpected System Shutdown
An abrupt power loss or an ungraceful system shutdown during a file system operation can leave ACFS metadata in an inconsistent state.
Underlying Storage Issues
Problems with the physical storage devices, such as disk failures or RAID controller issues, can lead to corruption of ACFS data and metadata.
Software Bug or Incompatibility
In rare cases, a bug within the Oracle ACFS software or an incompatibility with the operating system or storage drivers might cause metadata inconsistencies.
