Oracle Database Error ACFS-04003: Volume in Use Conflict
Description
This error indicates that an ACFS volume is currently in use or improperly mounted by a file system other than ACFS itself. It typically occurs during attempts to dismount, resize, or perform other management operations on an ACFS volume that is still actively mounted or has residual non-ACFS mounts. The system detects a conflict where the ACFS volume is not exclusively managed by ACFS.
Error Message
volume <volume_name> in use by a non-ACFS file system
Known Causes
4 known causesACFS Volume Still Mounted
The ACFS volume is currently mounted by the operating system (e.g., via `mount` command) and has not been properly unmounted before an ACFS operation.
Residual Mount Points
Even after an apparent unmount, there might be lingering or stale mount points or processes holding a handle to the volume, preventing a clean dismount.
Incorrect Unmount Sequence
Operations were attempted on the ACFS volume (like dismounting or resizing) before all applications or services using it were stopped and the volume was properly unmounted.
Non-ACFS Application Access
An application or process outside of the ACFS framework is actively accessing files or directories on the ACFS volume, causing the conflict.
