linux debian11 挂载硬盘 及 开机自动挂载

首先查看硬盘 : fdisk -l

root@debian:/usr/local# fdisk -l
Disk /dev/sda: 446.63 GiB, 479559942144 bytes, 936640512 sectors
Disk model: PERC H745 Adp   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 262144 bytes / 262144 bytes
Disklabel type: gpt
Disk identifier: AEA00544-8EC2-4211-92C0-4CD891A1306F

Device         Start       End   Sectors   Size Type
/dev/sda1       2048   1050623   1048576   512M EFI System
/dev/sda2    1050624 934637567 933586944 445.2G Linux filesystem
/dev/sda3  934637568 936638463   2000896   977M Linux swap

Disk /dev/sdb: 42.77 TiB, 47023449440256 bytes, 91842674688 sectors
Disk model: PERC H745 Adp   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 262144 bytes / 1048576 bytes

我要把42.77T的挂载

创建目录: **mkdir /data1 **

然后格式化42.77T的硬盘 mkfs.ext4 /dev/sdb

root@debian:/usr/local# mkfs.ext4 /dev/sdb
mke2fs 1.46.2 (28-Feb-2021)

挂载到刚刚创建的Data1:

mount /dev/sdb /data1

设置开机自动挂载: ** echo '/dev/sdb /data1 ext4 defaults 0 0' >> /etc/fstab**

查看是否挂载成功:** **cat /etc/fstab

root@debian:/usr/local# echo '/dev/sdb /data1 ext4 defaults 0 0' >> /etc/fstab
root@debian:/usr/local# cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# systemd generates mount units based on this file, see systemd.mount(5).
# Please run 'systemctl daemon-reload' after making changes here.

最下面显示你的硬盘信息 就OK了
