This is probably part of the NFS server, to catch when systems are being shut down and cleanly notifying and disconnecting clients. When the NFS mountd exports a filesystem, it gets a kernel lock on that volume/directory (the linux NFSd is a kernel thread, not a userspace daemon). I don't believe that the NFS server knows to un-export filesystems on a per-volume basis because it may come or go. If you expect the USB device to not be always connected, then you shouldn't export it as an NFS share. I don't think you can export an automount either. -- Jonathan Billings <billings at negate.org>
