Logical Volume Management (LVM)
https://www.howtoforge.com/linux_lvm
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
