I added /dev/sdb1 into /dev/VG_Storage01 3. did pvmove /dev/hdc2 /dev/sdb1 and pvmove /dev/hdd2 /dev/sdb1 4. removed /dev/hdc2 and /dev/hdd2 from /dev/VG_Storage01 5. created VG_Storage with /dev/hdc2 and /dev/hdd2 6. tried to extend /dev/VG_Storage01/LV_VG_STORAGE01: [code] vextend -l +100%PVS -r -t /dev/VG_Storage01/LV_VG_STORAGE01 Test mode: Metadata will NOT be updated.
