Thanks Mark Loic also gave me this link It would be a good start for sure Best regards -----Message d'origine----- De : ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] De la part de Mark Nelson Envoyé : mardi 14 avril 2015 14:11 À : ceph-users@xxxxxxxxxxxxxx Objet : Re: how to compute Ceph durability? Hi Ghislain, Mark Kampe was working on durability models a couple of years ago, but I'm not sure if they ever were completed or if anyone has reviewed them. The source code is available here: https://github.com/ceph/ceph-tools/tree/master/models/reliability This was before EC was in Ceph, so I'm guessing new models would need to be created for that, but this may at least be a good place to start.
