I'm not using EXT3 for the OS or the database, just for the LVM with
my recordings etc.  My OS is still on EXT3 and I have no plans on
changing that any time soon...especially since I tend to back up the /
and /boot partitions using the dump command.  From what I understand
that doesn't support EXT4.

I switched to EXT4 for recordings mainly so I can disable slow deleted
once all my older recordings are gone.

Again, my EXT4 recording partition works flawlessly on 2.6.31, so it's
hard to imagine it's a matter of EXT4 not being mature enough...unless
they somehow screwed up EXT4 in 2.6.32.
