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).
John.
