Linux報錯：read-only file system

使用scp傳輸文件以後linux系統忽然報錯 「Read-only file system」，而後就建立不了修改不了文件了，網上廣泛說是文件系統遭到破壞，有一個用於修復linux文件系統的命令：fsck ，運行以後提示以下：

root@bpi-iot-ros-ai:~# fsck 
fsck from util-linux 2.25.2
e2fsck 1.42.12 (29-Aug-2014)
BPI-ROOT contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
Block bitmap differences:  +33214
Fix<y>? yes

BPI-ROOT: ***** FILE SYSTEM WAS MODIFIED *****
BPI-ROOT: ***** REBOOT LINUX *****
BPI-ROOT: 55473/455168 files (0.1% non-contiguous), 422531/1817600 blocks
root@bpi-iot-ros-ai:~# 
root@bpi-iot-ros-ai:~# reboot

重啓以後就能夠正常使用文件系統了。
