Best Practice for Transferring Data To New Drive

Actually there is a way, if you use LVM. You can add a target disk to the same VG, mark the source PV as not allocable with pvchange -xn /dev/sdS (/dev/sdS is a source disk) and move PV to the other disk online with pvmove /dev/sdS. There is a risk, if the one of these disks would die during the move - you likely lose your data partially or at whole (because it’s a temporary RAID0 with zero redundancy).
