The number is rmtab (e.g. 0x000002) is like a reference count.  The
fact that you sometimes see '2' and sometimes '3' is of no real
interest.

I am correct in interpreting what you say as:

  When you fail over from 'a' to 'b', it does so quite quickly, but
  when you then fail back from 'b' to 'a', you get a 15 minute
  timeout?

If not, please explain in more detail.
If so:
  Why exactly are you doing this.  It doesn't seem to make sense.
  Did 'b' get rebooted in the interim?
  It could be that you are hitting the same issue discussed here:

    http://linux-nfs.org/pipermail/nfsv4/2008-June/008673.html

  and in the surrounding thread.

However this has nothing to do with sm-notify.
