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.Nor has EXT3 ever failed this (usually unintentional) test for me. I did have a reiserfs system fail to recover after a lockup (about 3 years ago), but I'm user the current reiserfs is stable now.
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.
