LVM - Add new disk and extend FS

LVM add "physical" disk and extend FS

• Make sure there is a Partition Table and a Partition for LVM

fdisk /dev/<disk>
>> create new gpt table: g
>> create new partition: n
>> set type of partition to lvm: t 
>> show partition codes: L
>> insert type: <type from L (Linux LVM)>
>> write changes: w

• Expand existing LVM VG

pvcreate /dev/<disk-partition>
vgextend <existing-vg> /dev/<disk-partition>

• Expand existing LVM LV

# find the correct logical volume
lvdisplay | grep Path 

# expand found lv
lvresize -l +100%free <lv path>

• Expand the ext4 filesystem on it

resize2fs <lv path>
