Creating and extending logical volumes

We currently have several PVs created and two of them grouped into a VG. Let’s move to the next layer and check the LVs with the lvs command:

[root@rhel-instance ~]# lvs
  LV   VG   Attr       LSize  Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  root rhel -wi-ao---- <8,00g
  swap rhel -wi-ao----  1,00g  

We see the root and swap volumes on the rhel VG, which hosts the operating system.

Now, we can create a simple LV called data, 200 MB in size, on the storage VG:

[root@rhel-instance ~]# lvcreate --name data --size 200MB storage
  Logical volume "data" created.
[root@rhel-instance ~]# lvs
  LV   VG      Attr       LSize   Pool Origin Data%  ...
