Ubuntu 挂载16T硬盘笔记

一、分区

查看硬盘信息

# 查看硬盘
sudo fdisk -l
# 下面是显示的硬盘信息

# Disk /dev/sda: 14.55 TiB, 16000900661248 bytes, 31251759104 sectors
# Disk model: ST16000NM000J-2T
# Units: sectors of 1 * 512 = 512 bytes
# Sector size (logical/physical): 512 bytes / 4096 bytes
# I/O size (minimum/optimal): 4096 bytes / 4096 bytes

设置硬盘信息

# 进入 parted
sudo parted /dev/sda
# 设置全部容量为 GPT格式
mkpart logical 0 -1

按照文章所说，默认进行分了一个/dev/sda1这个分区，但是我这里报了一个错误：

Error: /dev/sda: unrecognised disk label

经过查找，找到了原因，这是因为我并没有把硬盘标记为gpt，执行以下内容。
这里仅记录命令，注释记录一下，具体执行情况看最后面的完整记录。

sudo parted /dev/sda

# parted 内

# 设置为gpt格式
mklabel gpt
# 全部空间分到一个区
mkpart logical 0 -1

# 此处出现一个警告，我按文章的步骤直接输入了Ignore回车了。

# 查看分区结果
print 

# 输入 quit，退出 parted后ls检查一下，发现多了一个出来
quit

# 现在退出了 parted
ls /dev/sd*
# 结果显示多出来一个sda1： sda  sda1

二、格式化

这里注意，格式化执行过程中前面两三个一瞬间就好了，最后一个等待了好一阵子
Writing superblocks and filesystem accounting information

root@home:/dev# partprobe
root@home:/dev# ls sd*
sda  sda1
root@home:/dev# sudo mkfs.ext4 -F /dev/sda1
mke2fs 1.46.5 (30-Dec-2021)
/dev/sda1 alignment is offset by 3072 bytes.
This may result in very poor performance, (re)-partitioning suggested.

三、挂载

使用 sudo vim /etc/fstab 修改文件，在文件末尾补上以下内容
第一个参数是自己命名的，需要提前创建路径好像

/dev/sda1 /perry_hd_16 ext4 defaults 0 0

然后执行命令重新挂载

sudo mount -a

输入 df -hT 检查一下，看到了自己挂上去的东西，应该是OK了。

/dev/sda1 ext4 15T   28K   14T   1% /perry_hd_16

据说现在就可以开机自动挂上去了，完结撒花。

四、分区与格式化完整执行记录
