   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.

Good to know.  

I'll probably move to XFS when it becomes part of the
mainstream in the 2.6 kernel.  I hate patches, most especially patches
that aren't always compatible with the rest of kernel development. 
Also, in the past, not every distro has XFS support, so I would get into
the catch-22 situation of needing something from an XFS partition and
not being able to mount it.

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.
