<p dir="ltr">A variety of reasons. The biggest one for me is stability. XFS has been doing huge filesystems (>50gb) for years. ext4 hasn't. Today, I'd probably trust ext4 to do a 16 TB fs, but I'd still prefer XFS.</p>

I'm curious why it's an issue beyond that point. This indicates that<br>
ext4 has supported filesystems larger than 16TB for nearly two years:<br>

<br>
And Wikipedia says it now supports volumes up to 1EiB, or<br>
1,048,576TiB. See also<br>
