Hi,

I have set up a MySQL cluster following exactly this howto.

Page 1 is completed, but the problem I can see the nodes in ndb_mgm for a little while, and then I get

ndb_mgm> show;
Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2 (not connected, accepting connect from 192.168.0.101)
id=3 (not connected, accepting connect from 192.168.0.102)

[ndb_mgmd(MGM)] 1 node(s)
id=1    @192.168.0.103  (Version: 5.1.45)

[mysqld(API)]   2 node(s)
id=4 (not connected, accepting connect from any host)
id=5 (not connected, accepting connect from any host)

ndb_mgm>

So the questions is; How do I diagnostic this problem? Does there exist log files I can look in?
