No. A timeout is not a successful fence. The problem is why you're
getting the timeout in the first place now.

You can run stonith_admin and manually ack the fence, that should work.

No, as long as an old version is still around, that will be the DC and
the internal upgrade shouldn't happen.
I meant changes to the configuration that actually use new features. And
as soon as no more nodes running the old version are online, it'll
convert upwards too ...
But yes, we're already working on a new maintenance update for SP3 too.
