You do have a complete solution if you build a master/slave setup with
(at least) two replicating database servers.
You not only can use this for enlarging diskspace, but you need this for
database, kernel and hardware upgrades (or failure).
It all started with a database which needs 24/7 uptime. You can't solve
that with a solution for expanding diskspace for the database alone.
