Dear all, I have droplet which was with uptime about 2 years. Before an hour I got Error 500 on my all website which is hosted there. I am using WHM/cPanel installed on the server to manage it, but it's not accessible too now.

Can someone help me?
From the WHM/cPanel told me this:

I tried to restart cpanel for you and getting the error as :

=================================================
*** /usr/local/cpanel/etc/init/startup ERROR: ***
Refusing to start because log directory /usr/local/cpanel/logs is not writable!
The specific error was: Read-only file system at /usr/local/cpanel/Cpanel/LogCheck.pm line 29.
=================================================


your file system is in read-only mode, please ask you server administrator or service provider to run FSCK on your server.

after that you will need to run cpanel update

/scripts/upcp --force 

that will resolve the issue.

My web administrator is not online and will be back in few days, I can't wait those days, so can someone tell what exact can I do to repair my droplet?

PS. My Droplet is CentOS
