On the 16TiB max file size limit (not filesystem limit)
Dear ext4 developers
are there any plans to overcome the 16TiB maximum file size limit for ext4?
Now that resize works across 16TiB boundary, many people could be interested in using ext4 as a slower but safer alternative to a distributed filesystem for large storages. However 16TiB filesize limit might be a problem if one wants to do big virtualization or anyway somehow nesting storage systems one into the other. Is the limit hard to fix?
Thank you
S.

It would mean an incompatible on disk format change in the format of
extent. So it's doable but definitely not trivial.
