Fault tollerance should be done at a lower level than the filesystem.
Linux filesystems are used on many different devices, not just hard disks. Different devices can fail in different ways - a disk might have a lot of bad sectors in a block, a tape[1] might have a single track which becomes unreadble, and solid state devices might have get a few random bits flipped all over them, if a charged particle passes through them.
The filesystem doesn't know or care what device it is stored on, and therefore shouldn't try to predict likely failiures.
A RAID-0 array and regular backups are the best way to protect your data.
[1] Although it is uncommon to use a tape as a block device, you never know. It's certainly possible, (not necessarily with Linux).
