i had exactly the same problem with mysql server 4.1. if i just
unplugged ethernet cable on the other ndb node, the whole cluster went
down.
i have now been experimenting with mysql server 5.0.32 (or something
like that) and things have improved. yesterday i did all kinds of
tricks to a two ndb node cluster and didn't manage to break it.
sometimes though it took a quite long time to get the cluster initially
up starting to count when all processes were running.
also, i think that one still cannot alter ndb tables on the fly so
upgrading to next openser version will be a big hassle that no-one would
like to have in production environment.
so apart from alter table hassle, perhaps mysql cluster would now be
ready for prime time.
