Oracle Database Error ACFS-01047: Global Bitmap File Write Failure
Description
The ACFS-01047 error indicates that Oracle ACFS (Automatic Storage Management Cluster File System) failed to write an entry to its global bitmap file. This bitmap tracks space allocation within the file system, and its integrity is crucial for file system operations. This issue commonly occurs during file system operations or when ACFS attempts to update its internal metadata.
Error Message
write of global bitmap file entry failed
Known Causes
4 known causesInsufficient Disk Space
The ACFS file system or its underlying storage may have run out of free space, preventing ACFS from writing essential metadata updates to the global bitmap.
Incorrect File System Permissions
The operating system user or group under which ACFS operations are performed lacks the necessary write permissions for the ACFS global bitmap file or its containing directory.
Underlying Storage Device Issues
Problems with the physical storage device, such as corruption, bad blocks, or hardware failure, can prevent ACFS from successfully writing to its global bitmap.
ACFS Internal Metadata Corruption
The ACFS global bitmap file or other critical metadata may have become corrupted, leading to failures when the system attempts to update it.
