Hi
Latest versions (>= 2.02.171) of lvm2 provides this prompt:
# pvs
PV VG Fmt Attr PSize PFree
/dev/loop0 vg lvm2 a-- <30,00g <30,00g
# pvresize --setphysical 1T /dev/loop0
WARNING: /dev/loop0: Overriding real size 30,00 GiB. You could lose data.
/dev/loop0: Requested size 1,00 TiB exceeds real size 30,00 GiB. Proceed? [y/n]:
Regards
Zdenek
