this!
when I create a centos system, I let anaconda setup LVM, but I hugely
shrink /home to something reasonable, and leave much of the physical
disk space unassigned for future allocation. then I'll create a new LV
for /var/lib/whatever, mkfs_xfs and mount it (adding it to /etc/fstab)
when I want to explore something new like a database server, setup a web
server, or KVM... if it turns out I need more space for /home, its as
simple as..
lvextend -L +20g /dev/mapper/vg_xxxx-lv_home && xfs_growfs /home
to add 20G (or whatever) to said file system...
