How do I add disks to a Linux virtual machine?

I. VMware workstation menu bar virtual machine settings add hard disk next

ย 

II. SCSI next step:

Create a new virtual disk

IV. select the size of the hard disk you need ๐Ÿ‘‰ immediately allocate the disk ๐Ÿ‘‰ uncheck ๐Ÿ‘‰ store the virtual disk as a single file ๐Ÿ‘‰ next step

ย 

Five. Finish

Vi. after restarting the virtual machine, use the lsblk command to view the disk status

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

Discovery has successfully added a new hard disk sdb.

7. Create a new partition with fdisk

[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):

Then enter p, enter:

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

   Device Boot      Start         End      Blocks   Id  System

Command (m for help): 

Enter n enter:

Command (m for help): n

Enter p, 1, enter, enter:

Command (m for help): p

Command (m for help):

Enter w, enter, save and exit. At this point, the partition is complete.

8. Format with mkfs.ext4 command

View partition table first

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

It is found that the new partition is sdb1 (I only have one primary partition, so it is sdb1.) Then we format sdb1

[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

This completes the formatting.

IX. mounting area

I take the data directory attached to the root partition as an example:

New / data directory

[root@localhost /]# mkdir data

Mount partition to / data directory

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

View disk usage

[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

This completes the virtual machine add disk operation.
