WordPress: Error Establishing a Connection to the Database

This will be a short one, as I didn’t take screen shots, and I didn’t have to do much to resolve it. Just wanted to make note of it.

The other day I wanted to check my own site and instead of loading I got the message “Error Establishing a Connection to the Database”.

I applied my usual fix first; reboot. While the VM was rebooting it appeared there had been some disk corruption? the automatic fsck failed stating a manual fsck was required. so…

fsck /dev/sda1

and a bunch of “errors” and fix?<y>

after a bunch of answering yes, it stated the disk was repaired successfully.

after this I typed “exit”, and the system rebooted like normal. Lucky for me the WordPress site came up clean after that. However even had this had failed, we all have backups right?
