Hello

I installed mysql 5.0.7-beta3 cluster and it seems all running fine... it seems...

Here is the output of ndb_mgm "show":
ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @192.168.200.176 (Version: 5.0.7, Nodegroup: 0, Master)
id=3 @192.168.200.177 (Version: 5.0.7, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.200.175 (Version: 5.0.7)

[mysqld(API)] 2 node(s)
id=4 @192.168.200.179 (Version: 5.0.7)
id=5 @192.168.200.178 (Version: 5.0.7)

There are two data nodes (.176 + .177) and two sql nodes (.178 + .179).

Everything seems fine but when trying to get the status of those nodes I receive the following error:

ndb_mgm> 2 status
Node 2: started (Version 5.0.7)

ndb_mgm> 4 status
Node 4: not connected

ndb_mgm> 5 status
Node 5: not connected

The configuration file on the management node is:
----------------------------------------------------------

[NDBD DEFAULT]
NoOfReplicas=2
DataMemory=80M
IndexMemory=52M

[TCP DEFAULT]
portnumber=2202

[NDB_MGMD]
hostname=192.168.200.175
datadir=/var/lib/mysql-cluster

[NDBD]
hostname=192.168.200.176
datadir=/home/data/mysql/3306

[NDBD]
hostname=192.168.200.177
datadir=/home/data/mysql/3306

[MYSQLD]
[MYSQLD]

The configuration on the sql-nodes (/etc/my.cnf):
--------------------------------------------------------
[mysqld]
ndbcluster
ndb-connectstring=192.168.200.175
datadir = /home/data/mysql/3306

[mysql_cluster]
ndb-connectstring=192.168.200.175

Its not just the status message resulting in an error. Any start or stop operation doesn't have an affect on the sql nodes.

What's wrong?
