ACFS-02038
ACFS-02038: Incompatible Endianness File System
Description
This error indicates that an Oracle ACFS (ASM Cluster File System) cannot be mounted because it was created on a system with a different byte-ordering (endianness) than the current host. This fundamental architectural mismatch prevents the operating system from correctly interpreting the file system's metadata and data structures. It typically occurs when migrating or sharing storage between systems with different CPU architectures.
Error Message
File system created on an incompatible system (endianness). Cannot mount.
Known Causes
3 known causesCross-Platform Storage Migration
Attempting to mount an ACFS file system on a host with a different CPU architecture (e.g., big-endian to little-endian or vice-versa) than where it was originally created.
Shared Storage Endian Mismatch
Sharing a raw disk or LUN containing an ACFS file system between two nodes in a cluster or across different servers that have incompatible endian architectures.
Backup/Restore Endian Incompatibility
Restoring an ACFS file system backup onto a target system that has a different endian architecture than the source system where the backup was originally performed.
