They have a bunch of device-mapper, LVM, and XFS developers on staff though. So I don't think it's strange they're leveraging the people they already have. In a sense they are hedging their bets. From their perspective, if Btrfs pans out by community effort, then Red Hat can change their minds yet again and support it. And if it Stratis pans out better, in particular as it relates to support contracts, then at least they got a product they can ship and support. The open stratis question for me is, with so many layers it depends on, how are bugs going to get handled? And how fail safe will it really be when there are problems? And what do repairs entail, and how long do they take on large volumes? What sorts of goofy unexpected edge cases will users run into, and how long will it take to find workarounds and permanent fixes? Is it really offering both the general Linux community, including even Fedora in particular, something they'll really want? And I don't know the answer to any of that. I have no idea if it'll see widespread adoption like LVM has.
