一、查看设备

1、列出系统上的所有块设备：sudo fdisk -l

可以看到磁盘/dev/mmcblk0中还有剩余的空间未被分区。

2、打开需要进行分区的磁盘进行分区操作：sudo fdisk /dev/sdX

xxx@xxx:~$ sudo fdisk /dev/mmcblk0Welcome to fdisk (util-linux 2.31.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.GPT PMBR size mismatch (26769407 != 244023295) will be corrected by w(rite).

二、格式化

1、挂载可能会遇到的格式问题

xxx@jxxx:~$ sudo mount /dev/mmcblk0p15 /home/xxx/node
NTFS signature is missing.
Failed to mount '/dev/mmcblk0p15': Invalid argument
The device '/dev/mmcblk0p15' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?xxx@jxxx:~$ sudo fdisk -l /dev/mmcblk0p15
Disk /dev/mmcblk0p15: 87.2 GiB, 93673471488 bytes, 182955999 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

2、格式化

xxx@jxxx:~$ 
xxx@jxxx:~$ 
xxx@jxxx:~$ sudo mkfs.ntfs /dev/mmcblk0p15
Cluster size has been automatically set to 4096 bytes.
Initializing device with zeroes:  26%61%100% - Done.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.

三、挂载

xxx@xxx:~$ sudo mount /dev/mmcblk0p15 /home/xxx/node

开机挂载

xxx@xxx:~$ sudo vim /etc/fstab
# <file system> <mount point>             <type>          <options>                               <dump> <pass>
