solve the problem /dev/null: read only filesystem

本文介绍了一种解决Linux系统启动过程中遇到的只读文件系统错误的方法。通过使用initramfs环境下的临时shell,执行一系列命令使根文件系统可写,并修复了/dev/null设备的问题。
 

The problem is like :

......

Configuring kernel parameter dup2: bad file or desriptor name [failed]

/etc/rc.d/rc.sysinit 184 /dev/null read only filesystem

/etc/rc.d/rc.sysinit 184 /dev/null read only filesystem

/etc/rc.d/rc.sysinit 200 /dev/null read only filesystem [failed]

..............

Then enter "I" into repair file mode,excute the following command:

mount -o remount, rw /
rm -f /dev/null
mknod -m 666 /dev/null c 1 3

This remounts the root filesystem as writeable, then removes the device /dev/null, then recreates it with the correct permissions as a character device with the correct major/minor number.
