Quickly started running out of space.  Created a second physical volume and used vgextend to add it to the volume group.

~]# vgextend fedora_hpz440 /dev/nvme0n1p6

Increased the size of the logical volume with some of the space of the second physical volume.

 ~]# lvextend -L +150G /dev/mapper/fedora_hpz440/root

~]# vgdisplay fedora_hpz440

Still running out of space. df doesn't show any increase.
