We circle back for patch/upgrades only for break/fix. Stability means keeping the ABIs (and in general all interfaces and conventions) stable. It is very important when e.g. you intent to deploy some old Sybase on these boxes. How this type of stability helps the Ceph/KVM node ... ? I tried F19 just for the fun of it. We ended up with conflicts trying to run qemu-kvm with ceph. I could get one or the other working but not both. Our architecture is calling for compute and storage to live on the same host to save in hardware costs. I also tried to recompile libvirt and qemu-kvm today. I didn't even see rbd libraries in the source code. OSD/libvirt-kvm dual role node should work just fine with F19/F20. If you are interested in Fedora deployments, we could try to resolve these issues. Alek ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

I think this is a great idea. One of the big questions users have is
what kind of hardware should I buy. An easy way for users to publish
information about their setup (hardware, software versions, use-case,
performance) when they have successful deployments would be very valuable.
Maybe a section of wiki?
It would be interesting to a site where a Ceph admin can download an
API key/package that could be optionally installed and report
configuration information to a community API. The admin could then
supplement/correct that base information. Having much of the data
collection be automated lowers the barrier for contribution. Bonus
points if this could be extended to SMART and failed drives so we
could have a community generated report similar to Google's disk
population study they presented at FAST'07.
Would this be something like
http://wiki.ceph.com/01Planning/02Blueprints/Firefly/Ceph-Brag ?
It seems that all eyes are looking in the same or very close directions
:-)
Sage initially said wiki page per reference setup - outlined overview of
the context, specifics (e.g. defaults overrides and their reasoning),
possibly essential notes on some regular maintenance activities, etc. In
summary: the minimal readme or receipt enough for an admin to adapt
and replicate a proven setup.
Publishing of few concrete deployments in this form doesn't need any
development and will generate positive effect immediately - I'm doing
setup based on {wiki-page} with ... (differences), but ...
You (Loic) are developing on the practical basis for scaling all of this
at large: Convenient ceph-brag tool and online service - collecting of
detailed snapshot of the setup as it is visible from a Ceph node.
Kyle combines the two, saying: application of the collecting tool
followed by handcrafted shaping, linking and annotations before/after
publishing.
Personally, I most like Kyle's workflow - iterations of: tool based
collection - results in new version in the tool branch; applying fixes
trough the web editor - merging handcrafted defs branch;
publishing/communication.
Once the working prototype goes live, various derivatives could be
considered, e.g.:
* Nice, possibly interactive diagrams (visual documentation) of the
setup.
* Standard reports with anchors for referencing in the mails.
* Side projects for build and maintenance artifacts generation for
various management platforms - ceph-deploy or different (of course
assuming rejoining-back the private bits)
* View/Report aiming extracting the essentials, roughly equivalent to
the handcrafted Ceph setup receipt for the context.

Alek
