- For example, RAID devices are frequently bigger than the capacity
- of the largest individual hard drive.

- This option is not required if you have individual disk drives

+ The ext4 filesystem requires that this feature be enabled in
+ order to support filesystems that have the huge_file feature
+ enabled. Otherwise, it will refuse to mount any filesystems
+ that use the huge_file feature, which is enabled by default
+ by mke2fs.ext4. The GFS2 filesystem also requires this feature.
