Proxmox VE + OpenMediaVault使用lxc

安裝 debian LXC，並修正原磁碟大小

安裝 OpenMediaVault

修改debian lxc設定

nano /etc/pve/lxc/100.conf
#加入三行設定
lxc.mount.auto: cgroup:rw
lxc.mount.auto: proc:rw
lxc.mount.auto: sys:rw

更新 LXC 並且重新啟動 LXC： 
apt update && apt upgrade -y && reboot

新增OMV套件來源

https://openmediavault.readthedocs.io/en/latest/installation/on_debian.html

cat <<EOF >> /etc/apt/sources.list.d/openmediavault.list
deb https://packages.openmediavault.org/public usul main

新增 Zvol — 利用 ZFS 模擬實體硬碟

在先前建立的ZFS儲存池，建立使用omv使用的zfs磁碟

zpool list
zfs create -V 10GB local-zpool/omv-disk

查詢 Zvol 的實際位置

透過 ls -al發現是一個 link位置後發現是一個 link，再用 ls -al查尋他的真實位置

ls -l /dev/zvol/local-zpool/omv-disk 
lrwxrwxrwx 1 root root 9 Oct  4 14:41 /dev/zvol/local-zpool/omv-disk -> ../../zd0

fdisk /dev/zd0
