创建分区

原来是删除原来的/目录的分区，然后重新创建分区，注意删除/所在的分区时先不要w保存，最后创建新的分区再保存。

*fdisk mmcbllk1*

root@starfive:~# fdisk mmcbllk1

Welcome to fdisk (util-linux 2.38.1).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

fdisk: cannot open mmcbllk1: No such file or directory

root@starfive:~# fdisk /dev/mmcblk1

Welcome to fdisk (util-linux 2.38.1).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

This disk is currently in use - repartitioning is probably a bad idea.

It's recommended to umount all file systems, and swapoff all swap

partitions on this disk.

*输入d，然后输入4删除分区4*

Command (m for help): d

Partition number (1-4, default 4): 4

Partition 4 has been deleted.

*输入n然后输入4重新创建分区4，后面都直接回车按照默认参数*

Command (m for help): n

Created a new partition 4 of type 'Linux filesystem' and of size 28.7 GiB.

Partition #4 contains a ext4 signature.

*如下提示输入y*

Do you want to remove the signature? [Y]es/[N]o: y

The signature will be removed by a write command.

*输入w写入分区*

Command (m for help): w

The partition table has been altered.

Syncing disks.

*通知内核同步**partprobe /dev/mmcblk1*

root@starfive:~# partprobe /dev/mmcblk1

*再次查看分区lsblk，可以看到根目录/增加到了28.7G*

*扩容** resize2fs /dev/mmcblk1p4*

root@starfive:~# resize2fs /dev/mmcblk1p4

`resize2fs 1.46.6-rc1 (12-Sep-202[ 1019.864399] EXT4-fs (mmcblk1p4): resizing filesystem from 663291 to 7535360 blocks`

2) 

Filesystem at /dev/mmcblk1p4 is mounted on /; on-line resizing required

old_desc_blocks = 1, new_desc_blocks = 4

[ 1020.838282] EXT4-fs (mmcblk1p4): resized filesystem to 7535360

The filesystem on /dev/mmcblk1p4 is now 7535360 (4k) blocks long.

总结

通过阐述分区在重新创建分区，最后resize2fs扩展文件系统大小。

扩容后此时根目录就够用了，可以愉快的install程序了。
