    Monitoring a Ceph Cluster

    Ok, so you have gone through the five minute quickstart guide, learned a bit about Ceph, and stood a pre-production server up to test real data and operations…now what? Over the past couple of weeks we have gotten quite a few questions about monitoring and troubleshooting a Ceph cluster once you have one. Thankfully, our […]

    v0.55 released

    We had originally planned to make v0.55 a long-term stable release, but a lot of last-minute changes and fixes went into this cycle, so we are going to wait another cycle and make v0.56 bobtail.   A lot of work went into v0.55, however.  If you aren’t running argonaut (v0.48.*), please give v0.55 a try […]

    RBD support in CloudStack 4.0

    For the past few months I have been working towards a way to use Ceph for virtual machine images in Apache CloudStack. This integration is important to end users because it allows them to use Ceph’s distributed block device (RBD) to speed up provisioning of virtual machines. We (my company) have been long-time contributors to […]

    Ceph is the new black. It goes with everything!

    In my (rather brief) time digging in to Ceph and working with the community, most discussions generally boil down to two questions: “How does Ceph work?” and “What can I do with Ceph?” The first question has garnered a fair amount of attention in our outreach efforts.

    More Than an Object Store

    Today, Dmitry Ukov wrote a great post on the Mirantis Blog entitled Object Storage approaches for OpenStack Cloud: Understanding Swift and Ceph. Dmitry’s overview on Ceph was a solid introduction to those needing an object store for their OpenStack deployment, and it was an interesting read. Thanks, Dmitry! Naturally, since I spend most of my […]
