We are now running this - basically an intermediate/gateway node that

Hi,
That is awesome. We just Start in hacking ceph-deploy for gentoo And that will
definitly help us all.
We will test the code And looking forward to feedback.
Thanks to the gentoo-Folk @ceph ;-)

I've recently accepted the fact CEPH-FS is not stable enough for production
based on 1) recent discussion this week with Inktank engineers, 2)
discovery that the documentation now explicitly states that all over the
place (http://eu.ceph.com/docs/wip-3060/cephfs/) and 3) a reading of the
recent bug
Search the docs or mailing list archives for a discussion of the CRUSH
tunables; you can see that's the problem here because CRUSH is only
mapping the PG to one OSD instead of two. :)

Hi Dinu,
Initial tests for me using Ubuntu's 2013.2-0ubuntu1~cloud0 indicate that
live migrations do not work when using libvirt_images_type=rbd ("Live
migration can not be used without shared storage.") I'll need to dig
through LP to see if this has since been addressed.
