Considering the other possible options that have been mentioned, using the
Ext4 built-in larger devices support (which has been implemented recently)
seems to be your best bet.
https://askubuntu.com/questions/779754/how-do-i-resize-an-ext4-partition-beyond-the-16tb-limit

The required e2fsprogs version 1.43 is included in Ubuntu 16.10 by now, so you
don't even need to build it from the source.
https://packages.ubuntu.com/yakkety/e2fsprogs

But really, if you have everything on one array with a single huge filesystem
and no backups, that's just asking for trouble and a complete data loss.
