Open Stack

Thank you all for the prompt response. And I'm glad to see the progress on this topic.
Basically, what I'm thinking is the local storage support for big data and large scale computing is specially useful.

I'll monitor the meeting progress actively.

Duncan,
And I'm interested to know the details of this topic. Btw, if this Brick code called by Cinder?

Thanks
Emma

Subject: Re: [openstack-dev] [Cinder][Nova]Quest about Cinder Brick proposal

Hi all,

Emma,
thanks for raising this topic, I've added it for the next Cinder weekly meeting [1].

Duncan,
I absolutely agree with you that if any code could be located in a one place, it must be there.

I'm not sure which place is the best for Brick: oslo or stackforge. Let's discuss it. I want to be a volunteer to make Brick as a separate library and make OpenStack code better with re-using code as much, as possible.

Hi Emma

Brick didn't really evolve to cover the local storage case, so we've
not made much progress in that direction.

Local storage comes up fairly regularly, but solving all of the points
(availability, API behaviour completeness, performance, scheduling)
from a pure cinder PoV is a hard problem - i.e. making local storage
look like a normal cinder volume. Specs welcome, email me if you want
more details on the problems - there are certainly many people
interested in seeing the problem solved.

There is code in brick that could be used in nova as is to reduce
duplication and give a single place to fix bugs - nobody has yet taken
this work on as far as I know.
