..and some people simply don't care about this:

If you are running a 'big' Storage-System with battery protected
WriteCache, Mirroring between 2 Datacenters, snapshotting.. etc..
you don't need your filesystem beeing super-robust against bad sectors
and such stuff because:

a) You've paid enough money to let the storage care about
Hardware issues.
b) If your storage is on fire you can do a failover using the mirror.
c) And if someone ran dd if=/dev/urandom of=/dev/sda you could
even rollback your Snapshot.
(Btw: i did this once to a Reiser4 filesystem (overwritten about
1.2gb). fsck.reiser4 --rebuild-sb was able to fix it.)


..but what you really need is a flexible and **fast** filesystem: Like
Reiser4.

(Yeah.. yeah.. i know: ext3 is also flexible and fast.. but Reiser4
simply is *MUCH* faster than ext3 for 'my' workload/application).
