Description:
Hello, 
I was using MySQL CLuster 6.2 and 6.3 for while. 
I've decided to upgrade to 7 version. 
I kept the same configuration file. 
When I'm trying to start the storage engine in the servers, I have the following error: 

Forced node shutdown completed. Occured during startphase 4. Caused by error 2341: 'Internal program error (failed ndbrequire)(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node' 

The cluster worked very well under 6.3 version and now this error repeat everytime, I can't use it.

When I start the manager the node, then I start the datas, they can contact the manager but after 10 secondes, I have this error from the manager consol and the ndbd process is automatically killed in datas nodes.

How to repeat:
I've installed MySQL server 7.0.5 in a centOS 5 with the RHEL 5 packages.
Then i've try to start the nodes and I got the error

6.3 to 7.0 upgrade is not online(bug#44294) / filesystem.
you must backup/restore your 6.3 cluster,
start a 7.0 initial and restore...

Please use Jonas suggestion, or wait for 7.0.6 as it will be fixed in that version

Thank you very much.
I made the backup then restore and its works very well again
