OpenStack summit : Ceph design session

OpenStack summit : Ceph design session

[Loic Dachary]

[-- Attachment #1: Type: text/plain, Size: 882 bytes --]

Hi,

In anticipation of the next OpenStack summit http://www.openstack.org/summit/portland-2013/, I proposed a session to discuss OpenStack and Ceph integration. Our meeting during FOSDEM earlier this month was a great experience although it was planned at the last minute. I hope we can organize something even better for the summit.

For developers and contributors to both Ceph and OpenStack such as myself, it would be a great opportunity to figure out a sensible roadmap for the next six months. I realize this roadmap is already clear for Josh Durgin and other Ceph / OpenStack developers who are passionately invested in both projects for a long time. However I am new to both projects and such a session would be a precious guide and highly motivating.

Hi,

I would love to have such discussion. I think it's a good initiative.

Cheers.

Sounds like a great idea!
Thanks for putting together the session!

[Neil Levine]

Thanks for taking the lead on this Loic.

As a blueprint, I'd like to look at RBD backups to secondary clusters
within Openstack. Nick Barcet and others have mentioned ideas for this
now that Cinder is multi-cluster aware.

Great :-) Are there blueprints you would like to see in this session beside those you're currently working on ?

Hi Neil,

I've added "RBD backups secondary clusters within Openstack" to the list of blueprints. Do you have links to mail threads / chat logs related to this topic ? 

I moved the content of the session to an etherpad for collaborative editing

https://etherpad.openstack.org/roadmap-for-ceph-integration-with-openstack

and it is now linked from 

http://summit.openstack.org/cfp/details/38

Re: OpenStack summit : Ceph design session

[Neil Levine]

It's been an embryonic internal Inktank conversation and Nick Barcet
at eNovance mentioned some ideas when we last met. Will try and put
together a blueprint soon.

Hi Neil,

I've updated http://summit.openstack.org/cfp/details/38 with the Geographic DR related threads

    Geo-replication with RADOS GW http://marc.info/?l=ceph-devel&m=135939566407623&w=4
    Geographic DR for RGW http://marc.info/?l=ceph-devel&m=136191479931880&w=4

I'm increasingly interested in figuring out how it fits with OpenStack.

Cheers

Re: OpenStack summit : Ceph design session

[Neil Levine]

I think the multi-site RGW stuff is somewhat orthogonal to OpenStack
where as the RBD backups needs to factor in Horizon, Cinder APIs and
where the logic for managing the backups sits.

Ross is looking to get a wiki setup for Ceph blueprints so we can
document the incremental snapshot stuff and then use this as a basis
for creating the OpenStack blueprint.

Who approves the session at ODS and when is this decision made?

Great.

I suspect Josh knows more than I do about this. During the cinder meeting earlier today J. Griffith said that if the nova track is too busy to host the "Roadmap for Ceph integration with OpenStack" session he was in favor of having it in the cinder track. Following his advice I suggested to Thierry Carrez to open a "Cross project" track ( http://lists.openstack.org/pipermail/openstack-dev/2013-March/006365.html )

Good question.

Yehuda: how would the asynchronously replicated user metadata interact
with Keystone?

the interaction to copy the block device to a secondary location would
be triggered through a Cinder API call no?

Depends. Are there any special requirements? From what I understand,
you'd define the keystone backend every zone interact with per-zone,
and the fact that it's a replicated region/zone doesn't change much.

Hi Yehuda,

I'm not sure if one keystone for all zones would be better than one keystone per zone. If you think it's worth discussing during the OpenStack summit and you create a session http://summit.openstack.org/cfp/create in the keystone track, I will definitely attend :-). Or I can do it if you like. But there is no way to share the edit permissions.
