I am a very new Systems Administrator. I have a Windows background and am now a Jr. Systems Admin working with Cent OS 5. Our web server runs Cent OS 5 and uses PHP/MySQL for our web applications. Every morning when I come to work I receive emails from the data center that give me reports on the status of our servers. One of the pieces of data is the amount of usage (used space/remaining space) ... this is a small business and the last admin jumped ship. So I have minimal training on these specific systems and the documentation that was left can't possibly cover everything. This is what it reads:
Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.8G 7.3G 62M 100% /
As you can see above. That is a problem. Many clients use these web services. So if this was you ... what would your very first course of action be?
