Cannot add tables to MySQL cluster (no replies)

Here is the output from ndb_mgm > SHOW of my cluster setup:

ndb_mgm> SHOW
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @192.168.1.20 (mysql-5.1.47 ndb-7.1.5, Nodegroup: 0, Master)
id=3 @192.168.1.22 (mysql-5.1.47 ndb-7.1.5, starting, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.1.21 (mysql-5.1.47 ndb-7.1.5)

[mysqld(API)] 3 node(s)
id=4 @192.168.1.21 (mysql-5.1.47 ndb-7.1.5)
id=5 @192.168.1.20 (mysql-5.1.47 ndb-7.1.5)
id=6 @192.168.1.22 (mysql-5.1.47 ndb-7.1.5)

However, when I login to one of the mysqld nodes and try to create a table, I am given this error message:
ERROR 1005 (HY000): Can't create table 'clustertest.ctest' (errno: 711)

I've looked into it a little bit and the only explanation I can find is that one of the nodes is busy. I have not found anyway to fix this error.

Any help is appreciated.
