Indeed.

The "easiest" way to fix the alignment on an existing system is to create a new LVM PV, move LVs to the new PV, recreate the original PV correctly aligned, and move everything back.
That's something you can manage on a VM with enough available storage.
(Also, the misalignment/realignment will break deduplication on smart NAS/SAN storage, so you won't benefit from this.)

On a physical server or Smart-1 appliance, you need to shrink the existing PV, resize the hosting partition, create a new partition/PV, move LVs...

Anyway, you need to know what you're doing and make sure solid backups are not too far away.
