changed kernel, and rebooted my instance, did I lose my data?
I'm very new to running things on linux or any kind of server management in general. I had my website up on a DO droplet for a while now and noticed it started returning 502 responses. So after some digging on Google, for some reason I decided to change the kernel in the settings. Then I did a Power Cycle reboot then restarted via DO console. Then I found out that downgrading kernel from Ubuntu 14.04 to a lower version might cause problems. Everything I did above was in a state of panic and now I'm quite lost. Is my data intact, or did I make a huge screwup
