Rook – Open, Cloud Native, and Universal Distributed Storage in Alpha

Worth noting that it's a project connected to Quantum (http://www.quantum.com/)

Feels like a yet another storage startup in making

Aiming up to be bought by EMC in two years or so

From GitHub Usage looks simple. Quick question on the listed example, after creating 10MB new volume image. Later does it allow volume resize (say to 20MB) ?

So, it's an independent distribution of Ceph with a focus on ease of use. Not a bad goal. I just hope they don't complicate actual Ceph developers' lives by making outlandish claims about technology they don't understand.

I don't suppose anyone could say how this compares to Torus when using CoreOS?

Very interesting, what's the minimum amount of nodes required to operate it?

According to the link,

> It scales from a single node, to multi-PB clusters spread geographically

Couldn't they have improved ceph? - if it's a simpler ceph they want.

Alpha.

Like life.

Rook may be alpha, but they didn't start from scratch:

> rookd uses an embedded version of Ceph for storing all data

> rookd embeds Etcd to store configuration and coordinate cluster-wide management operations

Yes, I think this is what makes this project so interesting. It keeps Ceph in the data path which has been tuned over 8+ years while leaning on the stability and advances in etcd for consistent distributed configuration.

Good. Filesystems sometimes seem easy-ish, but starting from something fairly proven is a very good idea in this space IMO.
