Ubuntu will occasionally run a filesystem check every 30th (or so) bootup. Usually that happens when I am working on something, and don’t want to wait. But I also like to make sure my disk is error free, so I will occasionally run it manually. The gotcha here is you should NEVER run fsck on a mounted file system. But a simple command can cause a fsck run on the next reboot:

when the machine restarts, it will run fsck.
