No. (until you don't wrongly modify the crushmap manually) >>Is it possible to lose any? with replicat x2, if you loose 2osd on 2differents nodes, with the same object inside, you'll lost the object >>Is there a mechanism that prevents replicas to be stored in another osd in >>the same node? The Crush map ! ----- Mail original ----- De: "Azad Aliyar" <[email protected]> À: "ceph-users" <[email protected]> Envoyé: Vendredi 6 Mars 2015 11:08:47 Objet: [ceph-users] Multiple OSD's in a Each node with replica 2 I have a doubt . In a scenario (3nodes x 4osd each x 2replica) I tested with a node down and as long as you have space available all objects were there. Is it possible all replicas of an object to be saved in the same node? Is it possible to lose any? Is there a mechanism that prevents replicas to be stored in another osd in the same node? I would love someone to answer it and any information is highly appreciated. -- Warm Regards, Azad Aliyar Linux Server Engineer Email : [email protected] | Skype : spark.azad 3rd Floor, Leela Infopark, Phase -2,Kakanad, Kochi-30, Kerala, India Phone :+91 484 6561696 , Mobile :91-8129270421.
