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:
root@devninja ~ > lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
data pve twi-a-tz-- 16.38g 0.00 0.49
root pve -wi-ao---- 7.75g
swap pve -wi-ao---- 3.88g
root@devninja ~ > lvremove pve/data
Do you really want to remove active logical volume data? [y/n]: y
Logical volume "data" successfully removed
root@devninja ~ > lvcreate --name data -l +100%FREE pve
Logical volume "data" created.
root@devninja ~ > mkfs.ext4 /dev/pve/data
