I need to put together a whole presentation on this, but I'm not yet 
sure how much I can say yet.

For now I can say that gluster performs better and has a much better 
worst-case resolution. If everything else goes to hell, I have disks 
with files on them that I can recover on a laptop if I have to.

Of course when you ask the Inktank consultants (now Red Hat) about "What 
happens when it fails?" the answer is "It doesn't fail." Well guess what...

To be fair, though, I can't blame ceph. We had a cascading hardware 
failure with those storage trays. Even still, if it had been gluster - I 
would have had files on disks.
