  I truly wish I could say the same, but unfortunately that was one of 
the failings we could demonstrate fairly consistently. During a 2 hour 
evaluation before our Chief Justice, CEO, and CIO, as well as the 
management team, ext3 never did survive 5 hard resets in a row. We 
rebuilt the machines exactly the same, only difference being on an xfs 
filesystem, all packages were the same. xfs still, to this day, has 
never failed to recover itself, even under almost 100% load. We migrated 
our Informix database from raw logical partitions under AIX to xfs 
partitions under linux and the data set was monitored for corruption at 
the moment of impact with absolutely NO loss. Even our vendor who was 
previously only certifying their product under ext2 or 3 added an 
addendum to our supportfolio stating that they will support xfs and last 
week told us that "unofficially" xfs will become the defacto standard 
for their Informix/Linux/FACTS product line.
  As an aside, my copy of Linux Journal just arrived, with SGI's ALTIX 
3000 on the cover. It's the ultimate badass linux box, with up to 64 
Itanium2 64 bit processors, and 512GB ram, with a 512 processor/4TB 
memory version coming soon. This puppy ROCKS! Check out the filesystem 
performance chart, Figure 7, page 48 for a comparison.
  Ext3 works great for most people, but I've had and seen too many 
problems to consider it ready for a production machine in our 
environment. I'm glad you've had good luck with it though.
