    ViPR: A software-defined storage mullet?

    Almost every few weeks, new storage products are announced by competitors and I generally avoid commenting on them.

    What a Year 1!

    Back in January I posted about how Inktank’s momentum was accelerating. Well, to say this trend is continuing would be a gross understatement. The Inktank team continues to execute at a blinding pace and the world keeps on noticing. For example: •    The Community and Marketing (we are hiring) teams killed it at the OpenStack Summit. There […]

    Use existing RBD images and put it into Glance

    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…

    Ceph Community Expands “Geek on Duty”

    Last month Inktank launched a community help program that we called “Office Hours” in an attempt to provide specific hours where an engineer would be available to answer questions from the community.

    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. This functionality seems to have been introduced in 0.58 or so by commit c8f528a. So I gave it another shot with a build …Read more

    The Ceph Chef Experiment

    Sometimes it’s most interesting to just dive in and see what breaks. 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
