Re: Scaling MySQL Cluster
You can easily specify more [mysqld] sections that servers and then just start up new ones when needed. You can also carefully add them and do a rolling upgrade (see the archives for how).
Adding more disk storage, if really needed is just the standard way you would do it for your OS. If you wanted to do it online, adding a hotswap drive, extending your volume (using your favourite volume manager - e.g. lvm) and then resizing your filesystem is the way to go. I know XFS will do online growfs (xfs_growfs) and it takes next to no time.
Adding and removing NDB nodes requires a backup and restore. This is something we hope to change.
