ERROR 1005 (HY000): Can't create table (errno: 4336)

[Alan Aldrich]

I have set up a minimal cluster with 1 manager, 2 data nodes and 2 sql nodes
though the data nodes and sql nodes are the same two servers. Is this legal?

It seems to be setup correctly but when I go onto one of the sql servers and try to create a table using the syntax
mysql> create table btest (i int) engine=ndb;
I get this error
ERROR 1005 (HY000): Can't create table './foo/btest.frm' (errno: 4336)

my.cnf on each data and sql node looks like this
[mysqld]
ndbcluster
ndb-connectstring=192.168.44.130
[mysql_cluster]
ndb-connectstring=192.168.44.130


and config.ini on the manaemnet node looks like this

[NDBD DEFAULT]
NoOfReplicas=2
DataMemory=80M
IndexMemory=18M
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]
# Managment Server
[NDB_MGMD]
HostName=192.168.44.130 # the IP of THIS SERVER
# Storage Engines
[NDBD]
HostName=192.168.44.128 # the IP of the FIRST SERVER
DataDir= /var/lib/mysql-cluster
[NDBD]
HostName=192.168.44.129 # the IP of the SECOND SERVER
DataDir=/var/lib/mysql-cluster
# 2 MySQL Clients
[MYSQLD]
[MYSQLD]

This is Mysql 4.1.15 on FreeBSD 5.4

ndb_mgm shows this
oot@ndbmgr# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show

Any clues as to what I have wrong?
