Can not restart NDB cluster - Insufficent nodes

[Rait K]

made a rolling restart and this happened while restarting data nodes. no problem with management nodes, so there should not be any issue with config file
```
Status: Temporary error, restart node
Message: Insufficent nodes for system restart (Restart error)
