[Bug 1666853] [NEW] grub-probe when fs is larger than 2tb

[Elias Abacioglu]

Public bug reported:

don't really know if this is a resize2fs problem or a grub problem.
But we discovered it when trying to cloud-init bootstrap a node with larger than 2 TB disk.

Create a virtual or a physical node with more than 2TB disk.
install ubuntu cloud image on disk.
boot and let cloud init run it's course, after that grub2 os-probe will fail with this error message:
grub-probe: error: unknown filesystem.

Have tested this in both trusty and xenial
