Be careful before using the write command.

Command (m for help): wq
The partition table has been altered.
Calling ioctl() to re-read partition table.

如果遇到提示Re-reading the partition table failed.: Device or resource busy
用命令partprobe
初始化分区

mkfs.ext4 /dev/sdb1

挂载到本地

mount /dev/sdb1 /mnt/disk_1

查看磁盘使用情况

df -l

提示partition满了,解决办法
把swapper分区删掉(不是一个好办法,但是能解决问题)
通过fdisk -l查看哪个是swapp
swapoff /dev/sdb*
然后通过fdisk /dev/sdb删掉swapp分区,这样就多了个partition
