系统版本centos7.9 1、查看磁盘情况
[rootxus ~]# df -h

[rootxus ~]# fdisk -l
# /dev/vda已经做了分区

[rootxus ~]# fdisk /dev/vdb
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 .

Calling ioctl() to re-read partition table.
Syncing disks.4、格式化分区
[rootxus ~]# mkfs.ext4 /dev/vdb15、建立挂载目录
[rootxus ~]# mkdir /dataext6、挂载分区
[rootxus ~]# mount /dev/vdb1 /dataext7、设置开机自动挂载
[rootxus ~]# echo /dev/vdb1 /dataext ext4 defaults 0 0 /etc/fstab8.确认是否挂载成功
[rootxus ~]# df -h
