It's better to use the resize_inode for file systems that are smaller
than 16TB, even if the 64-bit flag is enabled, since using the meta_bg
style resizing spreads out the block group descriptors, which
increases the time to mount the file system. Using the resize_inode
will defer the need to go to the meta_bg-style resizing until we cross
the 16TB boundary.
Cheers,
