Hi,
At the linux symposium this week, some of us were wondering when it
would be safe to try and default ext3's default journal mode back to
sanity given that all (?) distros immediately reverted the default to
data writeback mode.
Well, at least SUSE still uses data=ordered,barrier as a default (and
I personally think this is the right thing to do). Hmm, maybe you've
meant this and just wrote it otherwise given your paragraph below ;)
Definitely what I meant to post - Fedora and RHEL both use ordered mode
as a default as well. Not many fs developers are fans of data writeback
mode as far as I can tell...
Failing that, can we at least clean up the config option description to
properly give the normal users a non-bogus, technical description of the
trade off ?
Yes, I'm all for it. Will you try to write up something or should I?

I posted something (from rwheeler@xxxxxxxxxx) earlier today and we had a
discussion about this on the ext4 call. I think that Ted will try to
update the text that I proposed over the next couple of days.
I think that Chris will be reposting his data guarded mode patches soon
as well, so we might be able to move forward quickly :-)
