【树莓派】U盘启动后无法Expand Filesystem

使用raspi-config进行Expand Filesystem会提示：

 sda2 is not an SD card. Don't know how to expand 

执行

# df -h

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        29G  4.2G   23G  16% /
devtmpfs        460M     0  460M   0% /dev
tmpfs           464M     0  464M   0% /dev/shm
tmpfs           464M   13M  452M   3% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           464M     0  464M   0% /sys/fs/cgroup
/dev/sda1        42M   21M   21M  51% /boot
tmpfs            93M     0   93M   0% /run/user/1000

再执行

# fdisk -l

Device     Boot Start      End  Sectors  Size Id Type
/dev/sda1        8192    93814    85623 41.8M  c W95 FAT32 (LBA)
/dev/sda2       94208 60063743 59969536 28.6G 83 Linux

/dev/sda2 已经是28.6G了

根本不用Expand Filesystem
我刷的是2017-09-07-raspbian-stretch

真需要手动扩展空间请参考：

• U盘安装树莓派系统，利用U盘启动Raspberry

到此结束
