# mkfs -V vxfs -o largefiles -s size special_device
Specifying largefiles sets the largefiles flag. This lets the file system to hold files that are two gigabytes or larger. This is the default option.
To clear the flag and prevent large files from being created:
# mkfs -V vxfs -o nolargefiles -s size special_device
The largefiles flag is persistent and stored on disk.
