Once fuser no longer returns any process IDs, there should not be any active processes in this file system, and the file system should now be unmountable. If the file system is still busy and will not unmount, the issue may be due to a kernel extension that is loaded but exists within the source file system. Determining what kernel extensions are open Processes are not the ONLY instances that can have open references. A loaded kernel extension can act as an open reference. To be more specific, if this file system contains kernel extensions and those files are in use, the file system will be unmountable until the references to those kernel extension files are closed as well.

Any kernel extension that is detected by this command that is referenced from the source file system must first be unloaded before the file system will be unmountable. Instructions to perform this are specific to the provider of the kernel extension.
