The press release de-emphasized CephFS, and bumped XFS while ignoring Ceph's BTRFS mode (where snapshotting is available).

CephFS (which is a distributed file system) is orthogonal to XFS or BTRFS which are local file systems. Since Gluster is providing a file system solution at this point, that may be the reason for the de-emphasis. However, Gluster is not a parallel file system, and Ceph is much better suited to fill that role. So I suspect CephFS will continue to be developed, if anything to compete against Lustre, PanFS, GPFS, etc..

Why do you say that GlusterFS is not a parallel file system? Certainly it is by the common definition of "file system that spreads data across multiple storage nodes."

I would really appreciate if somebody can clear this up for me: Can one mount Ceph on multiple nodes? (I'm referring to the CephFS part). I've worked with OCFS2 (which allows you to do exactly this) and liked it very much, but would've loved a clustered backing storage. Which is what Ceph provides.

Theoretically yes, but do note CephFS is not considered "production ready" AFAIK.

GlusterFS is much more focused on the filesystem bit, so why not give that a try, too?

Was in the same lab as Sage in grad school, and shared an advisor (Scott Brandt). He is super hard working, and definitely deserves this. Ceph was over 10 years of his life.

Fun fact - Sage was also the founder of webring, and simultaneously one of the dream host founders.

This is no coincidence. Ceph comes out of technology developed at Dreamhost.

Ceph is through and through Sage's work, it wouldn't exist without him.

Many CephFS features are directly tied to BTRFS features.

I would love to hear people's opinion's on what this means for ceph going forward? Will it change anything? It's telling for me that as the project starts becoming 'hot' RedHat step in. I totally get why it's a great strategic purchase in the context of winning cloud adoption / share / love.

I'm more interested in what it means for Gluster. I've had RH pushing Gluster at me very hard as performance-competitive with Ceph. Now they have Gluster and Ceph, it'll be interesting to see if Gluster falls by the wayside, or if they reposition Gluster more as easily-configured resilient storage.

That's because (a) CephFS isn't ready for prime-time (according to every talk I've seen at linux.conf.au in the last two years) and (b) the early push for btrfs as the underlying storage for Ceph has faded in favour of XFS until they're happier with the state of btrfs.
