With a cluster up and running and a mysqld attached I shutdown and restarted the cluster. I can not get the mysqld to attach and work on NDB related databases and tables until I restart the mysqld process.

It will give the following message:
The error message inside the mysql client was:
mysql> create table t1 (c1 int, PRIMARY KEY(c1))ENGINE=NDB;
ERROR 1005 (HY000): Can't create table './test/t1.frm' (errno: 4009)

Not bad, but being a good MySQLer I wanted to know what a 4009 was:

./perror --ndb 4009
OS error code 4009:  Cluster Failure: Unknown result: Unknown result error

How to repeat:
Setup a cluster with a mysqld process attached. Shutdown and restart the cluster. Try to do some work through a mysql client attached to the mysqd process.

Suggested fix:
reconnect to the cluster
