Linux虚拟机怎么添加磁盘?


一、VMware workstation菜单栏????虚拟机????设置????添加????硬盘????下一步

 

二、SCSI????下一步:

三、创建新虚拟磁盘????下一步

四、选择自己需要的硬盘大小????立即分配磁盘取消勾选????将虚拟磁盘存储为单个文件????下一步

 

五、完成

六、重启虚拟机后,使用lsblk命令查看磁盘情况

[root@localhost ~]# lsblk
NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda               8:0    0   20G  0 disk 
├─sda1            8:1    0    1G  0 part /boot
└─sda2            8:2    0   19G  0 part 
  ├─centos-root 253:0    0   17G  0 lvm  /
  └─centos-swap 253:1    0    2G  0 lvm  [SWAP]
sdb               8:16   0    5G  0 disk 
sr0              11:0    1 1024M  0 rom  

发现已经成功添加新硬盘sdb。

七、使用fdisk创建新分区

[root@localhost ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0x03295b0a.

Command (m for help):

然后输入 p  ,回车:

Command (m for help): p

Disk /dev/sdb: 5368 MB, 5368709120 bytes, 10485760 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x03295b0a

   Device Boot      Start         End      Blocks   Id  System

Command (m for help): 

输入  n  回车:

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): 

输入  p  回车, 1  回车,回车,回车:

Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-10485759, default 2048): 
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-10485759, default 10485759): 
Using default value 10485759
Partition 1 of type Linux and of size 5 GiB is set

输入  p  ,回车:

Command (m for help): p

Disk /dev/sdb: 5368 MB, 5368709120 bytes, 10485760 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x03295b0a

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048    10485759     5241856   83  Linux

Command (m for help):

输入  w  ,回车,保存退出。至此,磁盘分区完成。

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

八、使用mkfs.ext4命令进行格式化

先查看分区表

[root@localhost ~]# lsblk
NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda               8:0    0   20G  0 disk 
├─sda1            8:1    0    1G  0 part /boot
└─sda2            8:2    0   19G  0 part 
  ├─centos-root 253:0    0   17G  0 lvm  /
  └─centos-swap 253:1    0    2G  0 lvm  [SWAP]
sdb               8:16   0    5G  0 disk 
└─sdb1            8:17   0    5G  0 part 
sr0              11:0    1 1024M  0 rom 

发现新分区是sdb1(我只分了一个主分区,所以是sdb1。)然后我们对sdb1进行格式化

[root@localhost ~]# mkfs.ext4 /dev/sdb1 
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
327680 inodes, 1310464 blocks
65523 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=1342177280
40 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks: 
    32768, 98304, 163840, 229376, 294912, 819200, 884736

Allocating group tables: done                            
Writing inode tables: done                            
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

至此格式化完成。

九、挂载分区

我以挂载到根分区的data目录为例:

新建/data目录

[root@localhost /]# mkdir data

挂载分区到/data目录

[root@localhost /]# mount /dev/sdb1 /data

查看磁盘使用情况

[root@localhost /]# df -hT
Filesystem              Type      Size  Used Avail Use% Mounted on
/dev/mapper/centos-root xfs        17G  1.3G   16G   8% /
devtmpfs                devtmpfs  1.9G     0  1.9G   0% /dev
tmpfs                   tmpfs     1.9G     0  1.9G   0% /dev/shm
tmpfs                   tmpfs     1.9G   12M  1.9G   1% /run
tmpfs                   tmpfs     1.9G     0  1.9G   0% /sys/fs/cgroup
/dev/sda1               xfs      1014M  148M  867M  15% /boot
tmpfs                   tmpfs     378M     0  378M   0% /run/user/0
/dev/sdb1               ext4      4.8G   20M  4.6G   1% /data

至此,虚拟机添加磁盘操作结束。
