Comment 4 for bug 3581

From tune2fs(8) man page:

You should strongly consider the consequences of disabling mount-count-dependent checking entirely. Bad
disk drives, cables, memory, and kernel bugs could all corrupt a filesystem without marking the filesystem
dirty or in error. If you are using journaling on your filesystem, your filesystem will never be marked
dirty, so it will not normally be checked. A filesystem error detected by the kernel will still force an fsck on the next reboot, but it may already be too late to prevent data loss at that point.
