Let's hope btrfs is production ready before then because extX doesn't
look like a fitting filesystem for such big drives due their lack of
online fsck.
ext4's fsck is much faster than ext3's, and xfs's repair tool is also
pretty speedy.
Both are offline, but so far online fsck for btrfs is just a goal, no
(released, anyway) code yet AFAIK.
Isn't the speed improvement of ext4 achieved by not dealing with empty
extends/blocks? If so that wouldn't help you much if those 8TB are really
used. But even a speedy fsck is going to take longer and longer as
filesystem size grows which is why I believe we will soon reach a point
were offline-fsck simply isn't a viable option anymore.
I have a 30TB storage system that I chopped into ten individual volumes
because current filesystems don't really make creating a single 30TB fs a
wise choice even though I'd like to be able to do that.

Dennis
