Sorry, but what do I do now?

In all seriousness... SMART is a predicated failure, there are tools you can find which will dive a little deeper and let you know what kind of failures it is detecting, there are quite a number of them. If this is a critical system, don't mess around. Start verifying/taking backups and procuring replacement physical disks.
