Adding a new disk with LVM

Identify the new disk with:

lsblk

and add the disk as a physical volume:

pvcreate /dev/sdb

Verify it with:

pvdisplay

Now create a new virtual group with:

vgcreate myvg /dev/sdb

and finally a new logical volume (ensuring all space is allocated to it):

lvcreate -n mylg -l 100%FREE myvg

and verify with:

lvdisplay

and finally create a new filesystem on the volume:

mkfs.xfs /dev/myvg/mylv
