Description

Attempting to mkfs.lustre a disk below 16TiB in size but above the value computed for "resize" by mkfs.lustre (for 4KiB blocks, 32GiB shy of 16TiB) results in a failure as mke2fs requires resize to be greater than the specified capacity.

Example:
mkfs.lustre --ost --reformat --servicenode <elided> --fsname=lustrefs --index 1 --mgsnode <elided> --backfstype=ldiskfs /dev/ost1
