Linux虛擬機怎麼添加磁盤？

1、VMware workstation菜單欄👉虛擬機👉設置👉添加👉硬盤👉下一步

 

2、SCSI👉下一步：

3、建立新虛擬磁盤👉下一步

4、選擇本身須要的硬盤大小👉當即分配磁盤取消勾選👉將虛擬磁盤存儲爲單個文件👉下一步

 

5、完成

6、重啓虛擬機後，使用lsblk命令查看磁盤狀況

[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  

發現已經成功添加新硬盤sdb。

7、使用fdisk建立新分區

[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):

而後輸入 p  ，回車：

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): 

輸入  n  回車：

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

輸入  p  回車， 1  回車，回車，回車：

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

輸入  p  ，回車：

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):

輸入  w  ，回車，保存退出。至此，磁盤分區完成。

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

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

8、使用mkfs.ext4命令進行格式化

先查看分區表

[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 

發現新分區是sdb1（我只分了一個主分區，因此是sdb1。）而後咱們對sdb1進行格式化

[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。

9、掛載分區

我以掛載到根分區的data目錄爲例：

新建/data目錄

[root@localhost /]# mkdir data

掛載分區到/data目錄

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

查看磁盤使用狀況

[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，虛擬機添加磁盤操做結束。
