It checks the jfs filesystem on /dev/sda1. The v switch gives verbose
output so you can see what it's doing. The f switch tells it to go
ahead and check even if the filesystem is marked clean. Generally it's
a safe thing to do. It probably won't run if the fs is mounted, so if
it's your root fs you'll have to boot into safe mode, or from a live
CD, or with the drive in another system with jfsutils installed.
