You use an appliance, filesystem, or intermediate layer like lVM that allows you to add space and increase the filesystem on the fly. So JBODs with LVM on top and XFS on top of that could be resized on the fly. You can do the same with ext[34] as well (from memory). You can grow GPFS on the fly too - in fact we'll shortly be bringing up a new (larger) storage system, adding it to our GPFS pool and then telling GPFS to migrate data from the old system to the new one whilst the whole system is live. I think the same is possible with Lustre, GlusterFS and Ceph too. Then there are things like Panasas where you can buy more shelves and add them to the bladeset and expand that way. cheers!
