btrfs never got on my radar because it's Linux only and its instability
is a blocker. If I have to be careful how I use a filesystem even when
I didn't explicitly enable beta features, I'm too scared to put my files
on it. If I were a Suse Enterprise customer, I might use it, but Red Hat
isn't behind it anymore, so it's like Reiser3 back in the day. Only Suse
was putting their weight behind it. Well Facebook has developers on it,
but Facebook isn't a distro developer and can't be trusted with continued
maintenance, since they might switch on a weekend to some Facebook-FS.
Facebook has too many engineers and is reinventing stuff in-house a lot.

btrfs and zfs suffer from design limitations, but zfs has been stable
and in petabyte production for a long time across many organizations.
btrfs is one of many future Linux filesystems with no clear winner
so far. It looks like XFS will gain full checksums and scrubbing
before btrfs gets reliable and Red Hat's XFS++ work will provide
snapshots. It's like git replacing bitkeeper in 2005. Seems like
XFS++ will do the same with btrfs left to history of experiments.

All I want is a modern filesystem whose volume I can share without
exposing it via a network protocol.
