I've heard there is the plan to implement pvresize. The sequence below works. However, it requires reboot. -- vgcfgbackup edit file pvcreate --restorefile --uuid vgcfgrestore -- Not sure if new pvresize will do it on fly. May be somebody from lvm development team can answer this. Yes, I know that partitioning works. However, there is a restriction on the number of partitions.
