I've been using ext4 on '/' for a few months now. Seems to work
ok, but the worst that I've done has been sync-umount-boot with
Alt-SysRq when xorg locks. I think we're now at the stage where
ext4 is starting to get widespread use, which is why a lot of
odd corner-cases are now coming to light.
What _I'd_ *like* to do is move /home to ext4, because the periodic
fsck is so much faster, but some of my available systems are a bit
too old (ISTR the fs name changed, perhaps around 2.6.30). When I
started using ext4, I had fun and games getting systems to a point
where they could mount an ext4 partition, some needed e2fsprogs
and/or util-linux-ng upgraded, and one time I manged to build a
kernel without a necessary config option (CONFIG_LBDAF).
Similarly, my server should really benefit from ext4, but that holds
my backups and music/photos so I'll want experience with ext4
on /home on my desktops first.
For many people, ext4 is currently at least as good as ext3. As to
benchmarks, particularly at phoronix, I tend not to give much credence
to them. If you intend to try ext4, I suggest you create a new fs
and make sure you can correctly mount it, and perhaps run tests
if you are concerned about performance, before deciding to move
to ext4 for existing data.
After tragedy, and farce, "OMG poneys!"
