Description:
If I have a ten-node MySQL Cluster, and I run:

ALTER TABLESPACE ts1 ADD DATAFILE d1.dat INITIAL_SIZE=2G ENGINE NDB;

What happens?  Will it create a single virtual 2 GB "file" in ten parts, or will it rather create a 2 GB data file on each data node, for a total storage of 20 GB?

The docs are ambiguous here -- I think it could be read either way. 

How to repeat:
n/a

Suggested fix:
Clarify at http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-disk-data-objects.html

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.
