Those are not the same? In case 1 you tell LVM to drop a storage (I
assume by removing pv2 you first take it out of the vg and then apply
pvremove). In case 2 you you're simulating media failure to LVM. You
can't just remove a media it depends on. Regardless if LVM has data on
the PV or not.

Are you trying to make failover work? If so, your approach is a bit
wrong. Setup a software raid 1 first, then build your PV on that. Once
done, you can remove one disk and your LVM will continue to run
(degraded).
