Ubuntu file system on virtual machine becomes read-only mode solution

Virtual machine Environment Linux system because it is virtualized virtual out of the host environment, so often there are some operating system problems, today I encountered an Ubuntu operating system file system into a read-only mode, unable to operate the system, Because the problem of the host is my personal set of Hadoop Cluster name Master node, the whole cluster is more important, so on the internet also looked up some information, and then successfully solved the problem.

First of all, in the operation of the file times file system is a read-only mode can not operate the error, use the root user or other users with root privileges for system restart, using the reboot command to restart. This will take a while to wait, and then you will find that the system will go into the Initramfs interface, which needs to be based on the virtual disk name of your virtual machine to do the corresponding operation, such as my is sda1, then at the cursor flashing: fsck /dev/sda1 Command, Then enter Y for all of the file options that appear next, and exit the Initramfs interface with the last input exit, without accidentally entering the OS login screen.
