今天不小心把/etc/fstab改错了， 系统重启後显示
Checking filesystems
。。。。。。。。。。。。。。。
***An error occured during the file system check.
***Dropping you to a shell; the system will reboot
***when you leave shell. up to 100000000 @ 8000-d000
Give root password for maintenance
(or type Control-D to continue);
于是只能输入root的password进入, vi 打开/etc/fstab之后, 恢复为原来的样子但是保存时提示
-- INSERT -- w10: Warning: Changing a readonly file
改完後保存的时候提示
"fstab" E212: Can't open file for writing
:w! 也没有用
看来是mount成readonly 了.
于是
root# mount -o remount,rw /
再试vi /etc/fstab, 就可以保存了.
