How to upgrade from 6.3 to 7.0
+2 Vote Up -0Vote Down

In order to upgrade from 6.3 to 7.0 you must follow these rules:

  1. IT IS ONLY POSSIBLE TO UPGRADE FROM 6.3 to at least 7.0.6!
  2. I would recommend to upgrade from 6.3.x to 6.3.latest before doing the upgrade. If the upgrade does not work then and you have a good config.ini , you have probably hit a bug.
  3. You cannot upgrade from 6.3 to the multi-threaded binary of 7.0.6 in one go.
    You have to upgrade from 'ndbd' (6.3) --> 'ndbd' (7.0.6)
    Then you can do 'ndbd' (7.0.6) --> 'ndbmtd' (7.0.6)

So don't try to …

Configurator - new version 2.1
+0 Vote Up -0Vote Down

The Configurator has undergone some serious fixing as 2.0 had some issues.
Here is a brief list of the enhancements:

  • error handing and progress reports - I have rewritten almost all scripts with better error handling and progress reports. E.g, if a node fails to start during a rolling restart, then the rolling restart script is aborted and you get a suggestion how to recover. If you run start-cluster-initial.sh on an already started cluster, it will refuse to run. There are many more changes like this to check the status of the nodes (both data nodes and sql …
