Got error 1601 'Out extents, tablespace full' from NDB

[Michał Herman]

I am trying to do some tests on MySQL Cluster.
I am creating my database using following commands:

CREATE DATABASE test1;
use test1;
CREATE LOGFILE GROUP lg1
ADD UNDOFILE 'undofile.dat'
ENGINE = NDB;
CREATE TABLESPACE ts1
ADD DATAFILE 'datafile.dat'
USE LOGFILE GROUP lg1
ENGINE = NDB;
CREATE TABLE `dane` (
`id` int(11) NOT NULL,
`data` blob NOT NULL,
PRIMARY KEY (`id`)
)
TABLESPACE ts1 STORAGE DISK
engine=ndb;

Then I populate table with some data and random blobs 50KB each. But I am getting following error:

mysql> INSERT INTO dane(id, data) VALUES(3790, randomBlob(51200));
ERROR 1114 (HY000): The table 'dane' is full

mysql> select count(*) from dane;

1 row in set (0,03 sec)

It is not cluster memory usage problem:

ndb_mgm> ALL REPORT MEMORYUSAGE
Connected to Management Server at: localhost:1186
Node 3: Data usage is 6%(164 32K pages of total 2560)
Node 3: Index usage is 7%(178 8K pages of total 2432)

2500*50KB ~= 1GB
I have this error any time I am trying to insert more than 1GB of blobs.
How I can extend size of this tablespace?
