This is a known bug. There's a bugzilla entry:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=106936

The simplest workaround at the moment would be to issue a `service xinetd
restart`. That should clear the FAM daemon's hold on the process and
enable you to successfully unmount the drive. Also try adding the "lazy"
option to the command, i.e. `umount -l`.
