Create Mountpoint with Volume Group

README.md

General

If you want to create an mountpoint with Volume Group you can follow this step.

Topology

Case

• We have 2 disk (/dev/sdb & /dev/sdc)
• We want to combine that 2 disk to one Mountpoint (/mnt)
• We want to dynamicly extend that disk if we have a new disk

Create PV

pvcreate /dev/sdb
pvcreate /dev/sdc
pvscan
pvs

Create Volume Group

vgcreate vg01 /dev/sdb
vgs
pvs
vgscan

LV Create

lvcreate -L 9.99G -n lv01 vg01

Attach new disk to VG

vgextend vg01 /dev/sdc
pvs
vgscan

LV Extend

lvextend -l +100%FREE /dev/vg01/lv01

## or you can expand with single command like this
lvextend -l +100%FREE /dev/vg01/lv01 -r

Mount

sudo mkfs.ext4 /dev/vg01/lv01
sudo mount /dev/vg01/lv01 /mnt
lsblk

Detach PV

  • Before you follow that step, make sure you have an PFree LV to make pvmove success.

Refresh PFree after Online Extend

pvresize /dev/sdd
