MySQL Cluster restart

[thefusa]

Hi,
I've a mysql cluster.
I've modify the config.ini in order to increase some features.
When I restart my cluster (following the guide in this site)
ALL my db with ndbcluster engine was truncated!
All my dbs are empty!:confused::confused:

It's "nomal" that when I modify my config.ini all my db in cluster will be truncated?

thanks a lot
