http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-upgrade-downgrade-compatibility.html

These pages are missing an important information, which is if we need to specify --initial option to ndbd when doing rolling upgrade/downgrade. Stewert said that --initial option is required between some versions, but not every time. Please clarify when --initial option is required and write it to the reference manual.

I think it is safe to use --initial option everytime when upgrade/downgrade. So, the alternative is to make it default to use --initial option.

Discussed this issue with Jonas. He suggests that the best (and probably only) way to determine this is by testing an online upgrade between every Cluster release and the next higher one. I don't really have the resources to do this in a reasonable length of time - perhaps you can get someone in Support or QA to do so and then supply the results in this bug report.

Thanks!

BTW, Jonas also pointed out to me that we probably *don't* want to tell people "Just use --initial for all online upgrades" since this can make node restarts quite slow!

Reassigning to Mikiya as a reminder that I can't proceed until I have the needed info.
