LVM Cheatsheet

To install LVM2 in CentOS/Redhat servers:
yum install lvm2

1. Add a partition to physical storage/volume:
pvcreate /dev/sdb1 /dev/sdb2

2. Create volume group
vgcreate vg0 /dev/sdb2

(mention the partition where you want the volume group to be present)

3. Create logical volume:
lvcreate -L500G -n lv0 vg0

-n mentions the name of the logical volume.

4. Format your newly created logical volume:
mkfs.ext4 /dev/vg0/lv0
