Hello, your message is interesting. And also this thread:
https://www.redhat.com/archives/linux-lvm/2019-February/msg00002.html

But I'd like to know if I understood correctly.
Should I care about the physical disk size when I use LVM? Mixing disk 
with different sector size (512b and 4k) is dangerous?

Your message and others from the other thread, seems to say that LVM 
doesn't handle correctly that situation and that if I pvmove data 
between a 512b disk and a 4k disk (or viceversa), it will lead to a 
massive filesystem corruption. If I understood correctly, the problem 
that you described looks unrelated to encrypted volume and was only 
exacerbated by that. Right?

Cesare.
