LVM - pvmove to a smaller volume

  • 772

I would like to pvmove a logical volume to a smaller, but faster drive, leaving the excess part on the original drive. Can that be easily accomplished?

linux lvm arch-linux pvmove

    my understanding is that if you add additional PV (physical volume) to a VG (volume group) that hosts your LV (logical volume) you should be able to issue pvmove like so:

    # Move a range of physical extents to a
#       specific PV (which must  have  suffi‐
#       cient free extents).
       pvmove /dev/sdb1:1000-1999 /dev/sdc1

    taken from man pvmove
