# 刪除內建的 LVM thin:local-lvm，改用ZFS
1. 查看硬碟的分割狀態
**lvs**
```
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert

```
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
