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.

Please use more words.

i.e. please explain exactly what is happening. Leaving me guessing about
the bits that your aren't specific about doesn't help anyone.
