Note: it is similar to Creating a Ceph OSD from a designated disk partition but simpler. In a nutshell, to use the remaining space from /dev/sda and assuming Ceph is already configured in /etc/ceph/ceph.conf it is enough to: $ sgdisk … Continue reading →

Sage Weil, creator of Ceph, announced that Calamari – the Ceph web interface – will be open sourced, following Redhat’s acquisition of Inktank.

Inktank steered Ceph’s development, offered training and provided
support through an entreprise package which included Calamari: a web
interface to have insight on what is going on inside your cluster.
You can have a peek at what Calamari looks like here – in a session
from Portland’s Openstack Summit.
Now, what’s interesting is that prior to this announcement, Calamari
was closed source and would only be available as part of Inktank’s
entreprise package. The fact that Calamari was closed source resulted in
several open source alternatives spawning left and right – some of them
pretty good looking, too – to name a few:
I’m glad that Calamari will be open sourced, hopefully this means the
community will focus their efforts on one initiative. Having personally
worked on both python-cephclient and kraken, the programmer in
me is also curious as to how Inktank developed it. I can’t wait.

The jerasure library is the default erasure code plugin of Ceph. The gf-complete companion library supports SSE optimizations at compile time, when the compiler provides them (-msse4.2 etc.). The jerasure (and gf-complete with it) plugin is compiled multiple times with … Continue reading →

The gf-complete and jerasure libraries implement the erasure code functions used in Ceph. They were copied in Ceph in 2013 because there were no reference repositories at the time. The copy was removed from the Ceph repository and replaced by … Continue reading →
