====== 在 PBS(Debian 12) 主機內安裝 NFS 服務 ======
  * 安裝環境 PBS 3.0-3 (Debian 12.2)
  * 預計 NFS 分享的路徑 : /mnt/datastore/zfs-backup/nfsshare
  * 預計 NFS Client IP 範圍 : 10.20.0.0 - 10.20.2.254 -> 10.20.0.0/22

===== 安裝與設定程序 =====
  * 安裝 NFS 服務套件<cli>
apt update
apt install nfs-server -y
</cli>
  * 建立與設定分享目錄<cli>
mkdir -p /mnt/datastore/zfs-backup/nfsshare
chown 1000:1000 /mnt/datastore/zfs-backup/nfsshare
chmod 755 /mnt/datastore/zfs-backup/nfsshare
vi /etc/exports
</cli><file>
:
/mnt/datastore/zfs-backup/nfsshare 10.20.0.0/22(rw,sync,no_subtree_check,no_root_squash,all_squash,anonuid=1000,anongid=1000)
</file>
    * 關鍵參數解釋：
      * no_root_squash：允許 root 用戶保留完整權限
      * all_squash：將所有用戶映射到匿名用戶
      * anonuid=1000：指定匿名用戶的 UID
      * anongid=1000：指定匿名用戶的 GID
  * 啟動 nfs 服務與檢查狀況<cli>
exportfs -ra
systemctl restart nfs-server
systemctl enable nfs-server
systemctl status nfs-server
</cli>如果正常啟動會看到類似以下的訊息<cli>
# systemctl status nfs-server
