Hi! I just encountered the following and do not understand it. The confusing part is that when I run pvresize without size parameter directly after pvcreate, the size still seems to change even though pvcreate of course also uses the underlying device size just as pvresize should.
I am attaching the test.sh for your reference.
What am I missing?
