Ubuntu 20.04挂载14TB硬盘教程
ubuntu20.04如何新挂在一个14TB的HDD机械硬盘
在 Ubuntu 20.04 上挂载一个新的 14TB 机械硬盘，需要经过以下步骤：
1. 确认硬盘是否被系统识别
首先，检查硬盘是否已被系统检测到：
bash
sudo fdisk -l
或使用 lsblk：
bash
lsblk
找到目标硬盘（通常为 /dev/sdX，如 /dev/sdb 或 /dev/sdc，具体根据现有硬盘情况而定）。
2. 分区（可选但推荐）
如果硬盘是全新的，建议先分区。以 /dev/sdb 为例：
bash
sudo fdisk /dev/sdb
在 fdisk 交互界面中：
输入 n 创建新分区。
选择分区类型（默认主分区 p）。
设置分区号（默认 1）。
起始和结束扇区直接按回车使用默认值（占用全部空间）。
输入 w 保存并退出。
注意：如果硬盘大于 2TB，需使用 GPT 分区表。在 fdisk 中输入 g 创建 GPT 表，再继续分区。
3. 格式化分区
推荐使用 ext4 文件系统（适合大容量硬盘）：
bash
sudo mkfs.ext4 /dev/sdb1
如果硬盘需要更高性能或日志功能，可以添加 -m 0 减少保留空间（默认 5%）：
bash
sudo mkfs.ext4 -m 0 /dev/sdb1
4. 创建挂载点
选择一个目录作为挂载点（例如 /mnt/data）：
bash
sudo mkdir -p /mnt/data
5. 临时挂载硬盘
bash
sudo mount /dev/sdb1 /mnt/data
验证挂载是否成功：
bash
df -h
应能看到 /dev/sdb1 挂载到 /mnt/data。
6. 设置开机自动挂载
方法 1：通过 /etc/fstab 配置
获取硬盘的 UUID：
bash
sudo blkid /dev/sdb1
输出类似：
text
/dev/sdb1: UUID="1234abcd-5678-efgh..." TYPE="ext4"
编辑 /etc/fstab：
bash
sudo nano /etc/fstab
添加以下行（替换 UUID 和挂载点）：
text
UUID=1234abcd-5678-efgh... /mnt/data ext4 defaults 0 2
测试配置是否正确：
bash
sudo mount -a
若无报错，则配置成功。
方法 2：通过 disks 工具（GUI）
打开 Disks 应用（gnome-disks）。
选择目标硬盘和分区，点击齿轮图标 → Edit Mount Options。
启用自动挂载，设置挂载点，然后保存。
7. 权限设置（可选）
如果需要特定用户访问权限，修改挂载点所有者：
bash
sudo chown -R username:username /mnt/data
替换 username 为你的用户名。
注意事项
文件系统选择：对于 14TB 硬盘，ext4 或 XFS（适合超大文件）是推荐选择。
硬盘休眠：机械硬盘可能默认启用休眠，若需禁用，可添加 nobootwait 或修改 hdparm 设置。
数据安全：定期备份重要数据，大容量硬盘故障恢复成本较高。
完成以上步骤后，14TB 硬盘即可在 Ubuntu 20.04 上正常使用。

Ubuntu系统下如何挂载新硬盘2T及以下/挂载2T以上
10.将硬盘分区信息加入分区信息表，供系统识别。
echo "UUID=/dev/sdb1 /data1 ext4 defaults 0 0" >> /etc/fstab
不建议直接用/dev/sdd等挂载，建议用UUID：
ls -l /dev/disk/by-uuid/ 查看id
