Centos HDD, partition, format, mount

1. First look at how many drives are on the machine:

$ fdisk-l

2. Hard disk Partitioning

$ FDISK/DEV/SDD

N->p->1-> Enter, enter

It means creating a new primary partition, the size of which is the entire SDD disk

Last execute W, write to disk

The disk is now partitioned, but there is no file system, and the disk is still unavailable

Only one partition can be partitioned at a time, and multiple partitions need to be added multiple times.

3. Format the disk and write to the file system

$ mkfs.ext4/dev/sdd1

Wait for command execution to complete

4. Mount the new hard drive to a node on the operating system

$ MKDIR/MNT/SDD

$ MOUNT/DEV/SDD1/MNT/SDD

5. Execute the DF command to view the disk information and confirm that the new hard drive was mounted successfully

$ df

/DEV/SDD1 961432072 204436 912389636 1%/MNT/SDD

The above bold font is the new disk.
