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

• Check existing Volume Groups

vgdisplay
