Comment 17 for bug 134396

As a side note:

The ext2 and ext3 filesystems have an option to count the number of how often a partition was mounted and when it was last checked with fsck, and to enforce an fsck after it was mounted a certain times or checked more than a certain time ago. This option is configured per partition by means of the tune2fs command; see the -c and -i options of tune2fs in its manual page.

Of course, like any large-scale filesystem manipulation, an fsck is a very bad idea to run on a system whose hardware or kernel don't work reliably.
