View hard disk partition information # fdisk-L2. Use fdisk to specify the new hard disk format (/ dev/sdb), MBR format hard disk can only have up to 4 primary partitions # fdisk / dev/sdb 2.1. Create the primary partition [cqs@centos7 ~] $sudo fdisk / dev/sdb Welcome to fdisk (util-linux 2.23.2). The changes remain in memory until you decide to write them to disk. Think twice before using the write command.

The partition table has been altered!

Calling ioctl () to re-read partition table.

Synchronizing disks.

Note: finally, you must save and exit (w), otherwise the partition will become invalid.

Three: mounting

1. Create a new mount point [cqs@centos7 ~] $mkdir-p / home/cqs/data [cqs@centos7 ~] $mkdir-p / home/cqs/soft2. Select a partition to the specified mount point (temporarily mounted, it will fail after the machine is rebooted) [cqs@centos7 ~] $sudo mount / dev/sdb1 / home/cqs/data [cqs@centos7 ~] $sudo mount / dev/sdb5 / home/cqs/soft to check whether the hard disk can use [cqs@centos7 ~] $df

/ dev/sdb5 25669860 45080 24297780 1% / home/cqs/soft

Check whether the mount point is successful [cqs@centos7 ~] $mount | grep "sdb" / dev/sdb1 on / home/cqs/data type ext4 (rw,relatime,seclabel,data=ordered) / dev/sdb5 on / home/cqs/soft type ext4 (rw,relatime,seclabel,data=ordered)

Test the mount point for errors

# mount-a

Don't restart yet, use mount-a to test whether it can be mounted properly and then restart.

Take effect permanently

# echo "/ dev/sdb1 / home/cqs/data ext4 defaults 0" > > / etc/fstab

# echo "/ dev/sdb5 / home/cqs/soft ext4 defaults 0" > > / etc/fstab
