    The title of the article is not that explicit, actually I had trouble to find a proper one. Thus let me clarify a bit. Here is the context I was wondering if Glance was capable of converting images within its store. The quick answer is no, but I thin…

    v0.56.5 released

    Behold, another Bobtail update!  This one serves three main purposes: it fixes a small issue with monitor features that is important when upgrading from argonaut -> bobtail -> cuttlefish, it backports many changes to the ceph-disk helper scripts that allow bobtail clusters to be deployed with the new ceph-deploy tool or our chef cookbooks, and it […]

    Ceph Mania

    Ceph is super hot. When people tell me that storage can’t be sexy, I can’t help but feel like Ceph can be! I was out in our L.A. office last week, and the first thing I saw when I showed up was this: A Ceph fanboy working with a multi-petabyte deployment of Ceph decided to […]

    One More chef-client Run

    Carrying on from my last post, the failed chef-client run came down to the init script in ceph 0.56 not yet knowing how to iterate /var/lib/ceph/{mon,osd,mds} and automatically start the appropriate daemons.

There’s a Chef cookbook for Ceph on github which seems rather more recently developed than the one in SUSE-Cloud/barclamp-ceph, and seeing as its use is documented in the Ceph manual, I reckon that’s the one I want to be using. Of course, the README says “Tested …Read more
