Installation of a New Physical Volume

  1. Partitioning the physical volume:
    1. # fdisk /dev/XXX
      1. Command (m for help): n
      2. p
      3. Partition Number (1-4): 1
      4. First cylinder(1-..., default 1): <Enter>
      5. Last cylinder(1-..., default): <Enter>
      6. Command (m for help): t
      7. Hex code (type L to list codes): 8e
      8. Command (m for help): w
  2. Initialize disk for use by the LVM:
    # pvcreate /dev/<physical_volume#>
    1. If creating a new volume group.
    # vgcreate –s 32 <volume_group> /dev/<physical_volume#>
    1. If adding to an existing volume group.
    # vgextend <volume_group> /dev/<physical_volume#>
