It looks like tux2 is taking a different approach, and one of the goals is
total data integrity -- not just metadata. They are using phase trees.
It's been described as "failsafe" whereas XFS and most other journaling fs
are just "crash resistant".
I don't know if your database would like that approach. XFS makes sure my
database stays intact after a crash while the database itself (Progress 9)
manages the rest of the recovery process for stuff that it was working in
while it crashed.
Tux2 seems to be a really good idea for static content systems but I am
afraid that databases will not like phase trees.
I have not read the page yet so I might be all wrong ofcourse.
