In Proxmox 5.x-7.x LVM thin is the default local storage for VMs, However I prefer the old method of directory based storage for local storage, this article will show you How To Change Thin LVM to Directory Storage in Proxmox 5.x 6.x. You can find this information in the proxmox wiki. These are my terse notes to get the job done
To restore to old style storage like proxmox 4.2 and below. Please follow the steps below.
Change configuration settings on /etc/pve/storage.cfg
remove this line below:
dir: local
path /var/lib/vz
content iso,vztmpl,backup
lvmthin: local-lvm
thinpool data
vgname pve
content rootdir,images
After:
dir: local
path /var/lib/vz
maxfiles 0
content backup,iso,vztmpl,rootdir,images
Recreate /var/lib/vz
Type the following to set everything up
lvremove pve/data lvcreate --name data -l +100%FREE pve mkfs.ext4 /dev/pve/data
Result:

Edit fstab
In order for the hard drive to auto mount, make the fstab first in the file /etc/fstab
/dev/pve/data /var/lib/vz ext4 defaults 0 1
Restart proxmox host. Thats it.
