Getting Table got full error for "Disk Based Tables" (no replies)

Description:

I am trying to implement cluster for one of my client who has tables in 30 GB to 150 GB each and the total size of the DB is 1+ TB. They wanted to see how cluster might be suitable for their environment. They wanted mainly disk Based tables for this.

My config file

[ndb_mgmd]
Id=1
HostName=localhost
datadir=/dat/my_cluster/ndb_data
LogDestination=SYSLOG:facility=syslog;FILE:filename=/var/log/mgmd_1

[ndbd default]
NoOfReplicas=2
DataDir=/dat/my_cluster/ndb_data

DataMemory=2080M
IndexMemory=500M
MaxNoOfAttributes=10000
MaxNoOfOrderedIndexes=512

Created undo and tablespace from DB prompt instead of giving it through config file.

UNDO log files

NODEGROUP=0 INITIAL_SIZE=209715200 engine=ndbcluster;

TABLESPACE

USE LOGFILE GROUP ul_log EXTENT_SIZE 16777216 AUTOEXTEND_SIZE 8388608 ENGINE =NDB

DATA FILES

1) ADD DATAFILE 'tb1.dat' INITIAL_SIZE 8388608 ENGINE=ndb
2) ADD DATAFILE 'tb2.dat' INITIAL_SIZE 134217728 ENGINE=ndb;
3) ADD DATAFILE 'tb3.dat' INITIAL_SIZE 32212254720 ENGINE=ndb;

My doubts :

a) I am just loading 35 GB dump of a single partitioned table which is always getting table Full messages.

b) Is there a way to auto_extend a datafile from the initial size ?

c) Please help me out with proper variables that needs to be set for this disk based tables in ndbcluster.

I couldn't find lot of help from any docs so I am in need of some help terribly.

Thanks,
Santhinesh
