Linux挂载新硬盘


买的云服务器IDC给了一块10GB的数据盘,因为系统盘不大,就要把数据盘用上了



但是Linux下数据盘并没有挂载,Linux的磁盘系统也不同于windows,需要挂载使用



1、新建分区并格式化



使用


fdisk -l





查看当前的硬盘,可以看到有sda、sdb两块盘,第一块作为系统盘已经分区,sdb就是我们要挂载的数据盘



首先进行分区


fdisk /dev/sdb





进入磁盘sdb(如果你是磁盘sdc就相应的替换为sdc)相当于选中这个硬盘的意思



首先输入m看一下帮助






比较简单,应该很容易看懂,暂时把几个常用的写上了意思


Command (m for help): p                                        #显示磁盘信息
Disk /dev/sdb: 10 GiB, 10737418240 bytes, 20971520 sectors
Units: sectors of 1 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xb5106536

Command (m for help): n #新建分区
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p #新建逻辑分区
Partition number (1-4, default 1):
First sector (2048-20971519, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-20971519, default 20971519):
#直接留空,我只想把所有的空间分一个分区
Created a new partition 1 of type 'Linux' and of size 10 GiB.

Command (m for help): w #保存退出
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.





再次使用fdisk -l已经可以看到sdb有一个分区sdb1了






同Windows一样,磁盘需要格式化后才能使用





mkntfs /dev/sdb1


来格式化为NTFS格式,其他格式可以自行百度






出现


Cluster size has been automatically set to 4096 bytes.
Initializing device with zeroes: 100% - Done.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.


即为格式化完成



2、挂载磁盘








临时挂载可以使用mount命令,但是重启后需要重新挂载



用法为


mount 分区 目录


比如我需要使用


mount /dev/sdb1 /data


挂载






(当然前提是存在目录/data)



编辑


/etc/fstab


来永久挂载磁盘


# /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).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=22e202f3-ae04-4995-b214-de7f192f33c4 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=472580b3-a87b-4fe2-8bda-59b59d087ec6 none swap sw 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0
/dev/sdb1 /data ntfs defaults 0 0
磁盘 挂载目录 磁盘格式



需要注意的是,中间的空不需要打空格,用TAB制表符更方便

重启了一下,挂载确实成功了
