解决方法：
1.使用 fdisk -l 查看磁盘大小及分区情况（可以很明显看到，存储设备大小默认是 8 G 的，但实际只是用了 1G 多一点，明显还有很多剩余空间）：
root@BleachWrt:~# fdisk -l Disk /dev/loop0: 695.06 MiB, 728825856 bytes, 1423488 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 GPT PMBR size mismatch (2130463 != 16777215) will be corrected by write. The backup GPT table is corrupt, but the primary appears OK, so that will be used. The backup GPT table is not on the end of the device.

Partition table entries are not in disk order.
2.使用 fdisk 将空闲空间划分出来分区：
root@BleachWrt:~# fdisk /dev/sda
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.
GPT PMBR size mismatch (2130463 != 16777215) will be corrected by write. The backup GPT table is corrupt, but the primary appears OK, so that will be used. The backup GPT table is not on the end of the device. This problem will be corrected by write. 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. Command (m for help): n Partition number (3-127, default 3): First sector (2130432-16777182, default 2131968): Last sector, +/-sectors or +/-size{K,M,G,T,P} (2131968-16777182, default 16775167): Created a new partition 3 of type 'Linux filesystem' and of size 7 GiB.
