Hmm, for an HA environment, you're suggesting that a filesystem that
has been tried and tested for many years be dropped in favor of new
filesystems in experimental stages. I'm not so sure I agree with you
here. Granted, fsck times are a problem, but I'm not as confident in
ext3 and reiserfs as you seem to be.
As for ext3's data journalling, it was present before there was
metadata-only journalling. The tricky bits of implementing journalling
were limiting it to just metadata, not the other way 'round.
