All tables remove on ndbd --initial

[Tears !]

Dear All,

For some reason I had changed config.ini on management node.

After that I had kill (ndbd) on both storage nodes. And then again start
ndbd with ndbd --initial.

But when I had checked tables in my database there was nothing , all tables
were removed

Would you please help me how I can recover my old tables.

And what is the correct procedure to change config.ini and load again.

Regards,

Umar
