Hi Tayyab

That error was not very helpful, we should improve that.

A couple of guesses:

1) You do not have a nodegroup 3.
If you started with 2 nodes, and then added 2 more nodes, you will have two nodegroups, the first identified 1, and the second identified with 2.
Try "drop nodegroup 2" instead.
Note that while create nodegroup takes the node id that should form the new nodegroup, drop nodegroup take the node*group* number.

2) If you really have 3 nodegroups, you probably have some tables with data on the nodes in that nodegroup.

You can do "show" in ndb_mgm to see the nodes and their associated node group numbers, if you need more help please provide that output.


Regards,
Mauritz
