The title might not be as descriptive as I would like it to be but couldn't come up with a better one.
My server's file system went into Read-only. And I don't understand why it does so and how to solve it.
I can SSH into the server and when trying to start apache2 for example I get the following :
username@srv1:~$ sudo service apache2 start [sudo] password for username: sudo: unable to open /var/lib/sudo/username/1: Read-only file system * Starting web server apache2 (30)Read-only file system: apache2: could not open error log file /var/log/apache2/error.log. Unable to open logs Action 'start' failed. The Apache error log may have more information.
When I try restarting the server I get :
username@srv1:~$ sudo shutdown -r now [sudo] password for username: sudo: unable to open /var/lib/sudo/username/1: Read-only file system
Once I restart it manually it just start up without any warning or message saying something is wrong.
I hope somebody could point me into the right direction to resolve this issue.
