Oracle Database Error ACFS-03461: Cluster Node Unmount Failure
Description
This error indicates that an 'accel add' operation on an Oracle ACFS cluster was terminated because one of the cluster nodes failed to unmount its file system resources correctly. This typically occurs when a node cannot cleanly release its ACFS mounts, preventing the cluster operation from proceeding as expected.
Error Message
'accel add' aborted because one node of the cluster did not unmount properly
Known Causes
4 known causesActive Processes on ACFS
One or more processes or open files on the target node were actively using the ACFS file system, preventing a clean unmount operation.
Interconnect or Network Issues
Communication problems between cluster nodes or issues with the private interconnect prevented the node from signaling a successful unmount or receiving necessary commands.
ACFS or ASM Resource Lock
Other ongoing ACFS or ASM operations might have held locks or resources that prevented the specific node's ACFS from unmounting properly.
Underlying OS or Kernel Problems
Issues at the operating system level, such as hung processes, kernel panics, or resource exhaustion, interfered with the node's ability to perform a clean unmount.
