Creating LVMs

  • Partition disks as Linux LVM with fdisk
  • Prepare new partitions for LVM Example:
pvcreate /dev/sdb1 /dev/sdc1 /dev/sde1  # pvremove /dev/sdb1 /dev/sdc1 /dev/sde1 to revert
pvdisplay                               # to show Physycal volumenes
  • Create a volume group example 'pilaf':
 vgcreate pilaf /dev/sdg1 /dev/sdf1  # vgremove pilaf to delete
  • Check existing Volume Groups
vgdisplay
vgscan
  • Create logical volumes in volume group
lvcreate --name pilaf_copy --size 4T pilaf
lvcreate --name pilaf_converter --size 4T pilaf
  • Check existing logical volumes with:
lvdisplay / lvscan
  • Rename logical volumes with
lvrename {volume_group} {old_name} {new_name}  | example: lvrename pilaf pilaf_copy pilaf_raw
