Resizing Logical Volumes

• lvextend and ext2online can extend mounted ext2/3 filesystems

  • lvextend first grows the logical volume
  • you can not shrink mounted filesystems

• Physical volumes may be added to or removed

  • vgextend vg0 /dev/sdb1
  • pvmove /dev/hda3
  • vgreduce vg0 /dev/hda3
