飞牛将挂载盘挂载到本地目录

创建脚本和配置文件

创建挂载文件

​/root/mount_disk.sh​

#!/bin/bash
# 简单版：按 comment -> targetPath 映射 bind mount
# 配置方式 l_fn|/vol1/1001/Photos
MOUNT_INFO="/etc/mountmgr/mount_info.json"
MAP_FILE="/root/mount_map.txt"

if [ ! -f "$MOUNT_INFO" ]; then
    echo "找不到 $MOUNT_INFO"
    exit 1
fi
if [ ! -f "$MAP_FILE" ]; then
    echo "找不到映射文件 $MAP_FILE"
    exit 1
fi


# 遍历映射文件
while IFS='|' read comment target; do
    # 去掉前后空格
    comment=$(echo "$comment" | tr -d '[:space:]')
    target=$(echo "$target" | tr -d '[:space:]')

    # 跳过空行和注释
    [ -z "$comment" ] && continue
    case "$comment" in
        \#*) continue ;;
    esac

    # 从 JSON 找到 mountPoint
    mount_point=$(jq -r \
        --arg c "$comment" \
        'to_entries[] | .value | to_entries[] | select(.value.comment == $c) | .value.mountPoint' \
        "$MOUNT_INFO")

    if [ -z "$mount_point" ] || [ "$mount_point" = "null" ]; then
        echo "⚠️  未找到 comment=$comment 的 mountPoint"
        continue
    fi

    # 如果已挂载则跳过
    if mountpoint -q "$target" 2>/dev/null; then
        echo "⏩ 已挂载，跳过: $target"
        continue
    fi

    # 创建目标目录
    mkdir -p "$target"

    # 执行 bind 挂载
    echo "🔗 挂载: $mount_point -> $target"
    if ! mount --bind "$mount_point" "$target"; then
        echo "❌ 挂载失败: $target"
    fi
done < "$MAP_FILE"

创建挂载配置文件

​/root/mount_map.txt​

remote_dev_data|/vol1/1000/mnt_dev_data

1. 配置用 |​ 分割, 前面配置的是在飞牛挂载远程目录的 挂载名​ ,后面配置的是想要替换挂载的本地路径.

2. 多个挂载就配置多行.

添加权限

​chmod +x /root/mount_disk.sh​

创建开机启动服务

​vim /etc/systemd/system/mnt_truenas.service​

[Unit]
Description=mnt_truenas mount service
After=network-online.target
Requires=network-online.target
[Service]
Type=simple
User=root
ExecStartPre=/bin/sleep 10
ExecStart=/root/mount_disk.sh
Restart=on-failure        # 关键修改
RestartSec=30             # 失败后等待30秒重启
TimeoutStopSec=10         # 停止超时设置
[Install]
WantedBy=multi-user.target

更新systemd目录

systemctl daemon-reload

创建开机启动快捷方式

systemctl enable mnt_truenas.service

启动服务

systemctl start mnt_truenas.service

查看服务状态

systemctl status mnt_truenas.service
