How many hard drives does the Linux system have?

Use the df command to view.

df comes from the coreutils software package and comes with it when the system is installed; we can use this command to check the disk usage and the location where the file system is mounted;

Example:

[root@localhost ~]# df -l 
文件系统                 容量       已用       可用    已用% 挂载点 
/dev/sda3              4956316   3565088   1135396 76% / 
tmpfs                   241320         12    241308   1%   /dev/shm 
/dev/sda6              4806904   2523708   2039012 56% /media/disk 
/dev/sda1              4956284   3529796   1170656 76% /media/_ 
/dev/sda5              4845056   2581484   2019388 57% /media/disk-1

Note:

The partition format of the Linux system uses the xyzN format. xy represents the hard disk type. As shown in the above execution results, sd represents a SCSI hard disk and z represents The hard drive serial number, the first hard drive is a, the second hard drive is b, so to check how many hard drives there are on the Linux system, just pay attention to this. N represents the partition number.

Obviously, the Linux system in the example only has one hard disk.

lsblk This command can see how many hard drives there are, and each hard drive is divided into several areas
