We all know there's a file size limit 16TB in ext4 and other fs has their

If I create an qcow2 20TB on ext4 and write to it more than 16TB. Data more
than 16TB can't be written to qcow2.
So, is there any better ways to solve this situation?
I'd really just recommend using a different filesystem, in particular XFS
has massively higher file size limit - tested to 500 TB in RHEL-7, with a
theoretical max size of 8 EB. It is a very mature filesystem & the default
in RHEL-7.
