I'm not sure what the difference is, but I'm *shocked* that RHEL 7.4
is still using e2fsprogs 1.42.x.  There are a very large number of
resize2fs bugs, especially with very large file systems, with
e2fsprogs 1.42.x.  Especially in the case of off-line resizes with a
lage ext4 file system, with a resize2fs from e2fsprogs 1.42.x, data
corruption is almost a certainty.

If you have used resize2fs 1.42.x on that file system, I would suggest
running e2fsck on your large ext4 file system unmounted when you have
a chance, to make sure it's in a good and healthy state.
