I forgot to add that while I'm not sure if anyone ended up looking at the
last image I made regarding
https://bugzilla.kernel.org/show_bug.cgi?id=72801
I can generate a an image of that filesystem if that helps, or try other
commands which hopefully won't crash my running server :)
(filesystem is almost 2TB, so the image will again be big)
