..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).
