When running ndb_config --xml --configinfo on 7.0.10, the restart levels in the output are not the same as those listed in the docs on http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-params-ndbd.html

E.g., ndb_config lists MaxNoOfConcurrentTransactions as having a default restart type (i.e. node, not initial) while the docs lists this as requiring system restart. There are other inconsistencies too.

How to repeat:
Run ndb_config --xml --configinfo on 7.0.10+

Compare restart types with what's documented.

I'll repeat what I said earlier about this here:

Where does ndb_config get its info about required restart types?

How is this information derived?

If this is somehow more accurate than what Serge, Jeb, and I obtained through testing a couple of years ago, then I need to know about it, and where to get it. In which case this is a Docs bug, and it needs to be fixed, and someone needs to tell me where to get the correct info.

In any case, either ndb_config output is wrong or docs are wrong. In either case, we're giving customers wrong info about a critical aspect of Cluster administration, and this is not acceptable.

Raising this to P2/S2 on basis of the foregoing. Let's get some answers and do something about this ASAP.
