Oracle Database Error ACFS-05718: ACFS Filesystem Tree Mismatch
Description
This error indicates that a comparison between two internal tree structures within Oracle ACFS (ASM Cluster File System) yielded an unexpected difference. This typically occurs during filesystem validation, synchronization, or metadata operations, suggesting a potential inconsistency or corruption in the ACFS filesystem metadata. While the operation attempts to continue, it flags a significant internal discrepancy.
Error Message
An unexpected result occurred while comparing the first tree to the second tree. Continuing. Affected files: string string
Known Causes
4 known causesACFS Metadata Corruption
Corruption within the ACFS filesystem metadata can lead to discrepancies between internal data structures, causing tree comparison operations to fail.
Underlying Storage or ASM Problems
Issues with the ASM disk groups or the physical storage devices supporting ACFS can lead to data inconsistencies that manifest during tree comparisons.
Improper Filesystem Operations
Abrupt shutdowns, power failures, or incomplete filesystem operations can leave ACFS metadata in an inconsistent state, leading to comparison errors.
ACFS Software Defects
In rare cases, a bug within the Oracle ACFS software itself might cause incorrect tree comparisons or introduce inconsistencies during routine operations.
