刪除內建的 LVM thin:local-lvm，改用ZFS

1. 查看硬碟的分割狀態

1. 移除 local-lvm(/dev/pve/data)

   lvremove /dev/pve/data

   Removing pool "data" will remove 5 dependent volume(s). Proceed? [y/n]:y Logical volume "data" successfully removed

vgdisplay | grep Free

Free PE / Size 43705 / 170.72 GiB

使用 gparted live cd 調整lvm大小

使用文字指令parted

fdisk /dev/sdj 建立sdj4分割區

zpool create zfs /dev/sdj4

zpool list

進入資料中心，加入zfs 的儲存
